Question

A 680-Hz sound wave travels at 340 m/s in air, with a wavelength of

Answer 1

Solution:

we are given with

Frequency$=f=680 Hz$

Sound wave velocity$=V=340m/sec$

we have been asked to find the wavelength?

As we know that

$V=f \lambda$

$340=680 \lambda\\ \\ \lambda=\frac{340}{680} \\ \\ \lambda=0.5$

Hence the wavelength is 0.5m
