Question

Two identical mirrors are placed in a hollow cylindrical tube as
shown in the figure. A light ray incident on one of the mirrors
undergoes multiple reflections. If the length of each mirror is
3 m. and the velocity of light is 3*10^8 m/s. then find the time
taken by the light ray incident on the mirror to come out of thehollow cylinder​

Answer 1

Answer:

∴FromΔABC

12+1/22=AC2

AC=5–√2

∴ Distance travelled by the light ray.

d=6×5–√/2

65–√2

∴ Time taken dv=23×108=65–√×10−86s

∴ Time taken by light ray to reach point M is 5–√×10−8s
