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.
