Question

Why the second image formed due to reflection from the back reflecting surface is the brightest?

Answer 1

A thick plane mirror consists of two surfaces, (top and bottom) where the reflection can take place.

The images are formed after reflection from both the surfaces, except for the first image. The second image is the brightest of all as minimum absorption takes place and it bounces of the silvery layers which makes the bottom surface.

All successive images are formed due to multiple reflections and absorption and thus they are not as bright.

Answer 2

Answer:

hlo friend

as it is a thick plane mirror so reflection take place from both top and bottom surfaces,except the first image.

But second image bounces off the Silver surface and thus suffer minimum absorption .

All images after then go continuous reflection and intensity start decreasing after second image .

Thus 2nd image is brightest of all.
