Question

A wave of wavelength 0.60 cm is produced in air and it travels at a speed of 300 m s${}^{-1}$. Will it be audible?

• A. Yes
• B. No
• C. Data insufficient

Answer 1

The correct option is B

No

From the relation υ = v $\lambda$, the frequency of the wave is

$v=\frac{v}{\lambda }=\frac{300m{s}^{-1}}{0.60\times {10}^{-2}m}=50000Hz$

This is much above the audible range. It is an ultrasonic wave and will not be audible
