Question

Speed of a wave having frequency 300 Hz is 340 m/s. Find out its wavelength.

Answer 1

Answer on Question #40532 – Physics – Other

Speed of a wave having frequency $300\,\mathrm{Hz}$ is $340\,\mathrm{m/s}$. Find out its wavelength.

Solution:

$f = 300\,\mathrm{Hz}$ – frequency of the wave;

$v = 340\,\frac{\mathrm{m}}{\mathrm{s}}$ – speed of the wave;

Formula for the wavelength:

$$\lambda = \frac{v}{f} = \frac{340\,\frac{\mathrm{m}}{\mathrm{s}}}{300\,\frac{\mathrm{l}}{\mathrm{s}}} = 1.13\,\mathrm{m}$$

Answer: wavelength is equal to $1.13\,\mathrm{m}$.
