# Wave Speed - Fridge Physics

Wave speed is given in meters per second (the number of waves that pass per second). Wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second.

## Demo

In this tutorial you will learn how to calculate the speed of a wave.

The equation for this calculation is written like this:

$v = { \text f \; \text x \; \lambda }$

## Chilled practice question

Calculate the velocity of a wave with a wavelength of 6 m and a frequency of 50 Hz

## Frozen practice question

Find the velocity of a wave which has a time period of 10 s and a wavelength of 24 m, you will need to calculate the frequency from the wave period equation first.

## Science in context

Wave speed is given in meters per second (the number of waves that pass per second). Wave Speed = FrequencyWave length. Wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second.
