Episode 311: Speed, Frequency and Wavelength

These activities, from the Institute of Physics, consider how speed, frequency and wavelength are linked by the wave equation v = fλ . This is achieved by measuring frequency using an oscilloscope and measuring the velocity of sound in free air.

The activities include:
* worked example to deduce and use the wave equation
* exploring sound waves
* measuring frequency using a cathode ray oscilloscope
* measuring the speed of sound using a double beam oscilloscope
* investigating waveforms
