During reflection,
A) radiation is separated into several groups of weaker rays that travel in different directions.
B) radiation retains the same intensity but bounces back from the surface at a random angle.
C) radiation retains the same intensity and bounces back at the same angle with which it struck the surface.
D) a portion of radiation is absorbed by the surface and the rest bounces off of the surface.

Question

Quizplus · Accepted Answer

During reflection, radiation retains the same intensity and bounces back at the same angle with which it struck the surface. This is known as the law of reflection. Option A is incorrect as reflection does not separate radiation into weaker rays. Option B is incorrect as it suggests that radiation bounces back at a random angle, which is not true. Option D is also incorrect as it suggests that a portion of radiation is absorbed by the surface, which is not necessarily true for all types of surfaces.
