Year 10 IGCSE Physics class Cathode Ray Oscilloscope (CRO)

The Year 10 IGCSE Physics class has been learning how to use a Cathode Ray Oscilloscope (CRO) to analyse sound waves. They were investigating the relationship between the amplitude and loudness of a sound wave as well as the relationship between frequency and pitch. The students were also tasked with using the CRO to determine the time period and frequency of a range of sound waves.
