your question is incomplete. A complete question is ------> 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
solve :- frequency of sound wave = 300Hz
amplitude of a particle of the medium = 0.1 cm
we know, formula of maximum velocity = angular frequency × amplitude
angular frequency = 2π × frequency
= 2π × 300 rad/s
= 600π rad/s
now, maximum velocity of wave = 600π rad/s × 0.1cm
= 600π × 0.1/100 m/s
= 0.6π m/s
solve :- frequency of sound wave = 300Hz
amplitude of a particle of the medium = 0.1 cm
we know, formula of maximum velocity = angular frequency × amplitude
angular frequency = 2π × frequency
= 2π × 300 rad/s
= 600π rad/s
now, maximum velocity of wave = 600π rad/s × 0.1cm
= 600π × 0.1/100 m/s
= 0.6π m/s
