# Angle of incidence is equal to the angle of reflection. This is true :

A
always
B
sometimes
C
under special conditions
D
never
Solution
Verified by Toppr

#### Correct option is A. alwaysBy laws of reflection, angle of incidence is equal to the angle of reflection. Note that they may appear as unequal when surface is rough. However on a rough surface, due to the changes in the surface boundaries it appears unequal. At actually small surface area, angle of incidence equals the angle of reflection.
