Question

A bat emits shortest wave length in air is 0.33cm what is the highest frequency a bat can emit?if velocity of sound is 331m/sec

Answer 1

• Wavelength=$\lambda$0.33cm=3.3\times 10^-3m
• Velocity=v=331m/s
• Frequency=$\nu =?$

We know

$\boxed{\sf v=\nu \lambda}$

$\\ \sf\longmapsto \nu=\dfrac{v}{\lambda}$

$\\ \sf\longmapsto \nu=\dfrac{331}{3.3\times 10^{-3}}$

$\\ \sf\longmapsto \nu=100.3\times 10^3$

$\\ \sf\longmapsto \nu=0.1s^{-1}$
