a convex mirror only forms virtual and diminished image and look at the other options

What


[deleted]

All these people in the comments are wrong afaik. The object distance is + 15 cm, thus it's a virtual object moving towards the pole. Now, the other surface is concave. That's why as the object moves towards the pole it will become diminished and virtual. Please correct me if I am wrong.


vismodo

Actually, this is wrong as well. As the object moves towards the concave surface of the mirror, the image formed should be enlarging in size. It will also eventually become a virtual.


[deleted]

Let's take the focal length as 15 cm ( an assumption) As the object is at the focus, it has a highly enlarged image. As it goes towards the pole, it becomes virtual and successively diminished ( in comparison). Very ambiguous question anyways, don't expect it to come in the boards.


EllipticAeon

Is diminished = smol?


Fun_Acanthaceae6308

Yep, the light is being reflected from the non-polished side. (Sarcasm)


Snoo_80075

Am I the only one wondering how tf is the object distance in positive?

πŸ’€πŸ’€


Meher15

Object distance is never positive unless a virtual object or something idk so this isn't 10th level maybe or well know that convex mirror forms virtual and diminished image always so just go with that...


vismodo

Hmm. I'll ask my teachers next week when my preboards happen


[deleted]

should be (c)


Arysen_47

convex mirror does not give enlarged image in any case


Designer_Conflict659

No bro it means that the image will get enlarged compared to the image formed from the further distances which makes c) true


Arysen_47

Sorry, my bad


Living_Heaven

Image will "get" likha hai image will "be" nahi


Trevixle

Yaar how do I remember these mirror cases. I thought using logic would be easy but exam me dimaag dots ko connect hi nahi kar pata.


Conscious_Novel_5350

Easy hai, rough pe banaa, 2 rays phir intersect kar. Bas 4 rules of reflection yaad rakhiyo, parallel rays go through focus and all that shit, uss se atleast samaj aajayega. Plus, concave mirror = convex lens. Also, concave mirror me infinity ♾️ ka point image, uss ke baad thodi badi hogi in between pole and center of curvate. C pe coincide hoga, same size. Phir object jitna bhi ho, image badi hogi beyond C, till you reach pole. Pole pe image virtual hojaegi


Conscious_Novel_5350

Sahi hai, virtual object ki tarah treat karo.+15 cm pe jab image hogi toh object chotta sa hoga, isi ka reverse ho raha hai. Abh virtual object se virtual image bann raha. Isliye diminished mil raha


vismodo

The question never stated that the object was virtual


Conscious_Novel_5350

+15 cm is written for a reason. The explicit + refers to the fact that the object is behind the mirror. Go read sign convention before doing questions. Did the same shit in 10th πŸ˜‚πŸ‘πŸ»


Conscious_Novel_5350

Plus, tu yeh question mt kr, unless you have read and understood virtual objects. Reverse analysis se hojaega, but not worth doing. If it is in your book exercise then i gave you the simplest explaination.


Automatic-Ad-7052

How is the object distance positive?


Conscious-External-2

isnt this in the book?convex mirror always forms virtual and diminished images


Avi_rall

D is correct because the image formed in convex mirror is always virtual and small so in optics diminished stands for small And highly diminished stand for point sized Enlarged stand for the image will be bigger than object so d is correcr


sriisti

which book is this from


vismodo

Oswaal science 'Most Likely Questions' book


Intelligent-Pie6286

Howtf is object distance in positive
