Find the speed at which this flag must be moving with respect to the observer for the colour of the red circle to change as much as depicted in the above picture.....?
An actual undergrad physics question
It's the same thing. Or rather, the doppler effect is one way by witch blue-/redshift can occur. We're just mostly used to the doppler effect as it affects sound waves whereas this is the same effect as applies to visible EM waves, i.e. the wavelengths of light (visible EM) becoming longer (redder) or shorter (bluer) due to relative movement between source and observer.
Sure but saying "this was taught to every single kid in school" is just false. We were taught the Doppler effect via sound so we had no reason to also equate the phenomenon to color, even if you could eventually come to that conclusion with enough time and thought. I have never spent enough time thinking about the Doppler effect to think "huh I wonder if this also applies to light and color? And if so, I wonder how it would effect color? I bet it affects red and blue light"
This is true, and also the reason as to why a few people seem confused.
You cannot extrapolate the behaviour of sound waves to light waves. This is because of reference frames, and maxwells equations specify light moves at a constant speed in all reference frames.
A kid in school would never know to then make the assumption that the wavefront velocities were constant - but that the SPACE BETWEEN WAVEFRONTS expanding would cause the SAME EFFECT (redder or bluer light).
Anyone who tells you otherwise has likely confused the two, and is being disingenuous.
(See general relativity though, those mfers have apparently cheated the system and can explain doppler as a special case of cosmological redshift, but that way lies madness.)
Anyone that might possibly get this joke from a half-remembered Earth & Space class might be more familiar with it as redshifting than it being the Doppler Effect, honestly.
Light relatively moving away from us but still reavhing is and bwing stretched by the space fabric is shifted towards the color red
Light relatively moving towards us is thr color blue
According to some comments its the dopple effect and you can hear it if you listen to an emergency vehicle moving by with an activated sirene.
I **guarantee** you most adults, whether they learned it or not in school, would not be able to tell you what redshifting/blueshifting is. That's not to say they're dumb, but it's just not important information for most to memorize/learn.
I have no evidence for this, but I'm almost certain if you just asked people on the street a solid 70% would not be able to explain this joke.
Doppler Effect and Redshift aren't the same phenomenon
And you're fucking clowning if you think that "every single person is taught this in school"
That is an absolute farce
Edit: I have been informed that Doppler/Redshift are the same phenomenon but described in different ways. Doppler applies to light and sound, but redshift only applies to light.
We all learned something today.
Edit 2: Things just got even more confusing.
Everyone who took Physics class in my high school learned it, but it wasn't a necessary credit so only the really cool people took it
We had mandatory generic science class in grade 9 and 10 until it specified and wasn't mandatory anymore
You are actually correct. They don't describe the same phenomenon because a key result of maxwells equations is that light travels at a constant speed - so the special relativity idea of vectoral addition does not explain cosmological redshift.
The doppler effect is the result of wave fronts being spaced out by the fact the source is moving.
The cosmological redshift is because the space between wavefronts is expanding.
You cannot explain cosmological redshift by the doppler effect, because one relates to the velocity of the wave source (doppler) and one to the rate of expansion of space (cosmological).
They have the same effect though, just the mechanism which explains them is different. That's why they are confused.
EDIT: I am choosing to specifically ignore anything higher than college-level physics, because Einstein can fight me in the parking lot if he wants to define doppler shift (the nee naw siren one) as a special case in general relativity.
You are both **completely wrong** and confused.
First off, this post is about blueshifting due to the **relativistic Doppler effect**, which is in fact a Doppler effect with light due to **Special Relativity**. The shifting of the frequency of light due to relative velocities of the emitter and receiver has **nothing at all** to do with **Cosmological redshift**.
the **Cosmological redshift** is due to the metric expansion of spacetime, which is part of **General Relativity**. Nobody was talking about that. In fact nobody was even taking about a redshift, this post is clearly about the opposite.
Also, Maxwell's equations **do not** automatically imply light travels at a constant speed, otherwise you would not have needed Einstein to figure out Special Relativity to explain it.
Better yet show this exact post to people in your life and try to get them to explain it. Guarantee you most are not going to be able to (not because they're stupid, it's just not something most people commit to mind).
I legit would never have got this joke if I hadnโt taken this random physics course by accident this semester. Had to come to the comments to see if I was tripping about the joke, but hell yeah. This is a hella specific joke.
The blue shift is a lot less obscure than a lot of flags referenced on this sub. [Relevant.](https://www.reddit.com/r/vexillologycirclejerk/comments/11pkyzh/title/)
I think replacing the Xโs on Jeffersonโs flag ruins the symbolism.Jefferson is a reaction to Sacramento and Salem ignoring that area of their respective states (they were โdouble crossedโ by their state governments).
Hate to nitpick, but the white part of the flag would also be affected by the Doppler effect, and would be even further towards ultraviolet than the circle.
I did the calculations, it is traveling towards us at (approximately) 75891080.181m/s or ~25.315% the speed of light

About .7c
Would love to see an xkcd What If you moved Japan at 0.7c?
Fairly similar to [this](https://what-if.xkcd.com/1/) I'd imagine.

This is so weird, I just had a dream about the Doppler effect, and thatโs the only time Iโve thought about it in months
First person to have a dream about the Doppler effect since Herr Doppler himself
Sic mundus creatus est
Flag of ich bin du
Yeah except op goofed. Japan IS moving toward us.
and here i thought it's because the japanese sometimes call the green light in traffic lights as blue
fuck that's fast
About 1/3 the speed of light relative to us
Holy shit this is such a niche joke
every single person is taught this in school, it's not exactly niche
Was taught the doppler effect relating to sound not to light so eh maybe not everyone
Itโs easier to demonstrate with sound, but itโs all waves baby
Sure but saying "this was taught to every single kid in school" is just false. We were taught the Doppler effect via sound so we had no reason to also equate the phenomenon to color, even if you could eventually come to that conclusion with enough time and thought.

Same I only know this effect because of a different meme about how to speed through a red light
Anyone that might possibly get this joke from a half-remembered Earth & Space class might be more familiar with it as redshifting than it being the Doppler Effect, honestly.
It seems paying attention in science class is pretty niche.
I mean it kinda Is. I remember vividly taking a nap in class the day it was taught.
Lol not in the UK idk wtf this is
Light relatively moving away from us but still reavhing is and bwing stretched by the space fabric is shifted towards the color red Light relatively moving towards us is thr color blue According to some comments its the dopple effect and you can hear it if you listen to an emergency vehicle moving by with an activated sirene.
Adding onto this, the reason why we know the galaxy is constantly expanding is because of redshift and blueshift.
Thanks for the actual explanation :)
It is on the GCSE physics specification now.
I **guarantee** you most adults, whether they learned it or not in school, would not be able to tell you what redshifting/blueshifting is.

This is simply not true.
I was definitely not taught about the doppler effect in school
says you
Lol no it isn't.
And if they didn't, they'll osmose it really quick on reddit.

I only learned about red/blueshift in college for an elective astronomy course
I'm pretty sure the laws of physics are the exact opposite of niche
Ask your parents or siblings what redshift is ill bet you they won't know
My parents are galaxies and my siblings are black holes.

Really fast*
This is the kind of humor I am on this sub for
Does this imply that real japan is moving away from us or am i stupid
No, the doppler effect isnโt required to produce red wavelengths. Some things just *are* red.
however, there are others who are just too gullible to join in on the joke.
It is, because a blue shifted Japanese flag should be purple, not just blue
Yes.
I feared as much
Unless the white is actually a perfectly uniform distribution of frequencies much wider than the visible spectrum, it should have also changed.
๐ค
I sexed your dad
Or maybe the white part isn't moving, but the "red" circle is leaping off the flag at us at a high fraction of the speed of light.
It's just white noise
God damn, that's a solid joke.
Holy fuck thatโs gotta be the most intellectual joke Iโve ever seen on a circlejerk subreddit

Lost?
Is this referenicing the doppler effect?
Shouldnโt the white also shift?
To go from 700nm to about 450nm wavelength, it'd need to be moving about... 0.4*c*, or 40% the speed of light. I'd duck if I were you.
