Hi madam, how can we prove that 1) Image distance is equal to object distance 2) Image height is equal to the object height. In this video, you told that the triangles are congruent. Under which theorom, these triangles, become congruent? I understood Two angles are equal. What about the sides?
That is a good question, Meera. The 2 triangles are congruent because the opposite angles are the same, each has a right angle, and the heights of the triangles are also the same (because the beam parallel to the principle axis is reflected parallel to the principle axis, so the ray extension is also parallel to the principle axis).
Around 4:33: The eye receives light rays reflected by the mirror. Because the rays enter the eye in those particular direction, the person perceives the rays as coming from any points along that straight line, including the dashed part of the line. In this case, all the rays entering the person's eye appears to be coming from the same point behind the mirror. Therefore, the person gets the impression that the image is behind the mirror at that particular location.
A plane mirror is like a curved mirror with radius of curvature, r, that is infinity. Since f of a spherical mirror's f = r/2, it is reasonable to say that a plane mirror's focal length f is infinity. It also makes sense because light rays originating from the focal point (which is at infinity) get reflected by the mirror and come off of the mirror as parallel rays.
1:55 THANK YOU!!! I finally got this. First time I heard this explained, ever.
this video is so underrated!
and thank you i understand it much clearer
Wow amazing. Only video to clear my head and understanding. Thanks soo muchhh
you are so good you let the idea get in my head thanks
This has to be the best video explanation ever!
Thank you mam, very clear 👍
Awesome
thank you madam
Thank you very much that was so helpful
Thanks mam
Concept is fully cleared mam very nice I am from india
Very well made video. Thanks alot
Thank you for the post.
amazing
Thanks alot professure......

madam i enjoyed this video .Can you please make a video about bernoulis principle and coanda effect in wings of airplane.
nice ma'am
in some cases image is formed behind the mirror..then how we see it...???

px to the 5th power - 12 is equal or equivalent to P-x9 an accurate of 100% match
mam can u please tell me how to prove v=2x please
It's a focal length in the plane mirror please told me

Sorry it took me so long to respond. I do not understand what you meant by v = 2x
