10 Mirror formula and magnification

[tejkaransharma]

If the height of image is in negative so it will be real not virtual
And other mistake is that the image in not enlarge it's same in size

[thelistedpoint]

In case of concave mirror problem the image is not enlarge it is same as the object size

[cletusilondu]

I taught concave is +ve for a mirror and -ve for a lens ..am getting confused here 😕

[priyahirallihiralli]

The problem contains object height 5cm distance 10 cm from convex mirror which produces virtual image of height 3cm find the focal length of the mirror and position of mirror

It was very helpful but can u make some more twisted questions cause this is basic... thank you

[chitranoel]

Object size is 6 cm...image size is _ 6 cm...that means real inverted and same size....but you said it is enlarged... please correct that answer ❤️🙏🎉

[husseinhassan]

The mirror is concave so.the focal length is positive and not negative. if am not wrong. Thanks

[gautham.a]

9:15 'f' should be -ve, isn't Mam plz reply

[flarenceflarance]

Only if you watch full video you can understand

[shaikameer]

I don't understand when should we add when should we subtract...if you show that it will be better yo understand

if the height of image and object is 6 com
how can it be enlarged?

[shrutisinghrathore]

Height of the object was 6cm and the height of the image was -6cm again (it's -ve because it's inverted) so how's the image enlarged? It's same size
Also, recalling that case of concave mirror in which we place the object at C and then get the real image of the object at C itself of same size. Here in this question we can apply that case therefore the image is not enlarged

[pallavibisht]

in 1st numerical why the size of the image is enlarge

[tejuugaripalli]

When the the image distance is 30cm and object distance is 30 cm it would reflect at 'c' same size not enlarged here how can it enlarged ??

[vanshbisla-deyp]

Most of questions having linear magnification is 6

[pastorobej]

+ve is real and -ve is virtual for concave mirrors😊

[bdharaneshx-b]

Thanks for your video it is very helpful for my exam

[nineninja]

How to find the distance of the object? What is the formula of (u)

[madhuri]

Nice video even though I am studying ssc Ts but it helped me and solved the problem with mirror and magnification formula Anyways thanks for my school page

[rounakchakraborty]

hate to say formula is wrong it wud be
1/v - 1/u = 1/f
