(Choose from: Rectilinear propagation/Interference)
Observe the adjacent figure. AB and BC are two plane mirrors arranged at . A ray incident at angle at AB. Find the value of 'x'.
The angle of reflection is equal to angle of incidence when the light ray gets reflected from a smooth surface.
Name the type of mirror used in a periscope.
A periscope works on the principle of _____ of light from plane mirrors.
Light changes its _____ (direction/ speed/ frequency) when it is obstructed by any object, and it is called reflection.
In a periscope, the angle between the plane mirrors and the ends of periscope is:
