The phenomenon that results from the speed of light changing as it passes into different substances is:
A) reflection.
B) refraction.
C) interference.
D) internal reflection.
E) diffraction.

Question

Quizplus · Accepted Answer

The phenomenon described in the question is refraction, where the speed of light changes as it passes through different substances, causing it to bend. Reflection (A) occurs when light bounces off a surface, interference (C) occurs when two or more waves combine and either reinforce or cancel each other out, internal reflection (D) occurs when light is reflected back into a substance at an angle greater than the critical angle, and diffraction (E) occurs when light waves spread out and bend around obstacles.
