Vedclass · Answer

(B) Given:Speed of sound $(v)$ = $339\, m\,s^{-1}$Wavelength $(\lambda)$ = $1.5\, cm = 0.015\, m$Formula: $v = 
u 	imes \lambda$, where $
u$ is the frequency.$
u = v / \lambda = 339 / 0.015 = 22600\, Hz$.The audible range for human beings is $20\, Hz$ to $20000\, Hz$.Since $22600\, Hz > 20000\, Hz$, this sound is ultrasonic and will not be audible to human beings.

$A$ sound wave travels at a speed of $339\, m\,s^{-1}$. If its wavelength is $1.5\, cm$, what is the frequency of the wave? Will it be audible?
