Answer to Question #206446 in Physics for kenken

Question

What happens to the wavelength of a wave when the frequency decreases?

Answer 1

The relationship between the wavelength of the wave and frequency can be written as follows:

$$\lambda=\dfrac{v}{f},$$

here, $\lambda$ is the wavelength of the wave, $v$ is the velocity of the wave and $f$ is the frequency of the wave.

As we can see from the formula, if the frequency decreases the wavelength of the wave increases, as long as the velocity of the wave remains constant.
