Question
In experiment of resonance tube for determination of speed of sound, the intensity of sound at resonance will decrease if
Options
A.Water is replaced by mercury.
B.Water is replaced by oil.
C.Area of cross-section of the tube is increased.
D.Area of cross-section of the tube is decreased.
Solution
Sol. As area is increased, same power is distributed in more volume, hence less intensity.
