Question

During reflection of sound on a plain surface if sound makes an angle of 47 degree with normal then angle of reflection of sound will be? 1. 46 degree 2.47 degree 3.94 degree 4.74 degree

Answer 1

Sound is a form of energy which gives us sensation of hearing.

During Reflection, Sound obeys laws of reflection :

1. Angle of incidence and angle of reflection are equal.
2. Incident ray, reflected ray and normal at the point of incidence, all lie on the same plane.

Hence: option ii
If Incident angle is 47 ° then According to laws of reflection, angle of reflection is 47
