Question

Ryan while verifying the laws of reflection of sound measured the angle between the incident sound wave and reflected wave to be 130°.what is angle of incisence?..class9

Answer 1

Hi friend
---------------
Your answer
--------------------

Law of reflection of sound
-----------------------------------------

Given that : -

Angle between incident wave and reflected wave = 150°

We know,
------------------

Angle of incidence = Angle of reflection

Therefore,
-----------------

Angle of incidence = (180° - 150°)/2 = 30°/2 = 15°
