Question

Which phenomenon occurs when a wave encounters a non–transmitting barrier

Answer 1

C. reflection of the wave with the same wave speed

Step-by-step explanation:

A. refraction of the wave with a different wave speed

B. reflection of the wave with a different wavelength

C. reflection of the wave with the same wave speed

D. refraction of the wave with a different wavelength

Plato said C was right

Answer 2

Absorption

Step-by-step explanation:

A non-transmitting barrier would not allow a wave to go through. When a wave is unable to pass through a barrier, it is not transmitted and can get absorbed or reflected back. The wave can also try to go round the barrier.

Most likely, the wave gets absorbed by the barrier and it stops it.
