Prachi while doing an experiment to verify the laws of reflection of sound , measured the angle between the incident and the reflected sound wave to be 120 degrees . The angle of reflection is?

Answers (1)

In case of reflection, we know that angle of incidence = angle of reflection, and the normal bisects the whole angle.

Given  angle of incidence + angle of reflection = 120 degree

That means, the angle of incidence=angle of reflection =60o
