When a DVD is played, a laser light hits the surface of the disk and then returns to the detector.

Which wave phenomenon allows the DVD player to work?

A. absorption

B. interference

C. reflection

D. refraction

Are you on Edge trying to finish quickly? no worries, the answer is C.

Answer: The correct answer is reflection.

Explanation:

Refraction: It is the phenomenon in which the ray of light gets refracted when it travels from one medium to another due to the change in the speed of the light.

Reflection: It is the phenomenon in which the light gets bounces back from the barrier when it incidents on the barrier.

Interference: It is the phenomenon in which there is a superposition of the waves occur.

Absorption: The light wave gets absorb when it falls on the black body.

In the given problem, when a DVD is played, a laser light hits the surface of the disk and then returns to the detector. Here, the reflection phenomenon allows the DVD player to work.

Therefore, the correct option is (C).
