34. While doing the experiment on laws of reflection of sound four students Rahul, Rajesh,
Ranjit and Ramesh made observations in the following manner.
Rahul: For moving the incident wave 10° towards the normal with respect to the sound
reflecting board the reflected wave moves 10 away from the normal.
Rajesh: For moving the incident wave 10° towards the normal with respect to the sound
reflecting board the reflected wave moves through the same angle towards the normal.
Ranjit: For moving the incident wave 10° towards the normal with respect to the sound
reflecting board the reflected wave norms 20 away from the normal.
Ramesh: For moving the incident wave 10° towards with the normal with respect to the
sound reflecting board the reflected wave towards 20° towards the normal.
