Question

during reflection of sound on a plain surface if sound makes an angle of 47 degrees with normal then angle of reflection of sound will be?

Answer 1

angle of reflection of sound is 47 degrees. according to law of reflecton angle of incidence equals angle of reflection.given in question is angle of incidence

Answer 2

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