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

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

C. Reflection of the wave with the same wave speed

Explanation:

Reflection occurs when waves bounce back from a surface they cannot pass through.

Reflection can happen with any type of waves, not just sound waves. For example, light waves can also be reflected. In fact, that’s how we see most objects. Light from a light source, such as the sun or a light bulb, shines on the object and some of the light is reflected. When the reflected light enters our eyes, we can see the object.

Reflected waves have the same speed and frequency as the original waves before they were reflected. However, the direction of the reflected waves is different. When waves strike an obstacle head on, the reflected waves bounce straight back in the direction they came from. When waves strike an obstacle at any other angle, they bounce back at the same angle but in a different direction.
