Q. When a sound wave of frequency 300 Hz passes through a medium, the maximum displacement of a particle of the medium is 0.1 cm. the maximum velocity of the particle is equal to
A) 60 cm/s
B) 30 cm/s
C) 60 π cm/s
D) 30π cm/s
Explanation
(c) Maximum velocity $v_{\max\ }fa = 2 \times 300 \times 0.1$
$= 60\pi\ cms^{- 1}$
