Answer:
Option B is correct
Step-by-step explanation:
Reflection occurs when a wave hits a surface and bounces back
Reflection can be defined as :-
- Reflection is the change in direction of a wavefront at an interface between two different media so that it returns to the medium from which it originated.
- Light, music and water waves are all examples of reflection.
- According to the law of reflection, the angle at which the wave is incident on the surface equals the angle at which it is reflected.
- Specular reflection occurs in mirrors.
- Reflection produces echoes in acoustics and is used in sonar.Reflection at VHF and higher frequencies are crucial for radio transmission and radar.
- Even hard X-rays and gamma rays can be reflected at shallow angles using special "grazing" mirrors.
