A ripple tank can be used to measure and calculate frequency, wavelength and the speed of waves on the surface of the water it contains. It is a transparent shallow tray of water, with a light shining down through it onto a white card below, to more easily see the motion of the ripples created on the water’s surface. Ripples can be made by hand but to generate regular ripples it is better to use a motor.
To measure the frequency, wavelength and speed of waves in a ripple tank.
Here is an example of how the results table could look:
|Lengths of 12 waves (cm)||Wavelength (cm)||Number of waves in 10 seconds||Frequency (Hz)||Wave speed (cm/s)|
State the frequency, wavelength and speed of waves measured in this ripple tank.
|Electrical components near water||Shock, damage to goods||Secure electrical components before adding water taking care not to splash|
