Question

when a sound wave of frequency 300hz passes through a medium the maximum displacement of a particle in medium 0.1 cm then what is the maximum velocity of that particle​

Answer 1

Explanation:

Thus, the particle in the medium is in a simple harmonic motion. The maximum velocity of the particle is 60πcm/s. Thus, option (D) 60πcm/s is the correct answer

Answer 2

Answer:

60πcm/s

Explanation:

The displacement of the particle of the medium is:

x=Asin(kx−ωt)

Velocity of the particle of the medium is:

v=Aωcos(kx−ωt)

Max velocity of the particle v  

max

​  

=Aω=A×2πf=0.1×2×π×300=60πcm/s
