Question

seema while verifying law of reflection of sound measure the angle between the incident sound wave and reflected sound wave to be 150.what is the angle of incidence

Answer 1

Heya...

The angle of reflection = 150°......(given)

We know,
Angle of incidence = angle of reflection

So, angle of incidence = 150°

Answer 2

hii
according to the laws of reflection angle of incidence is equal to angle of reflection

         
        angle of incidence = 150
