Question:

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

always

sometimes

under special conditions

never

Solution:

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