Answer to Question #309427 in Physics for Physics

Question

Sound travels through air at a speed of 342 m/s at room temperature. To the nearest tenth of a meter, what is the wavelength of a sound wave with a frequency of 285 Hz?

Answer 1

Given:

$v=342\rm \: m/s$

$f=285\rm \: Hz$

The wavelength of a sound wave

$$\lambda=\frac{v}{f}=\frac{342}{285}=1.2\:\rm m$$
