Physics required practical waves

Waves required practical

Materials: ripple tank plus accessories, suitable low voltage power supply, metre ruler

Speed – this will be calculated using the equation: wave speed = frequency x wavelength

Wavelength – it is likely that a metre ruler will be used to measure across as many half wavelengths as possible. Then divide the total length by the number of half waves. Multiplying this number by two will give the wavelength

Frequency – it is likely that no apparatus will be used. The frequency will be the frequency of the power supply. It may be suggested that a stroboscope is used. This will ‘freeze’ the pattern to show a transverse wave. The frequency of the stroboscope is then the frequency of the waves.

Risk assessment: Water is easily spilt onto the floor. Mop up all spills straight away. Place any…
