Edexcel IGCSE Physics 3.3 Wave Definitions Questions

Amplitude is the maximum displacement from the rest position; wavelength is the distance between matching points on a wave. Frequency counts oscillations per second, period is the time for one oscillation, and a wavefront joins points in the same phase.

Exam points

measure amplitude or wavelength from a diagram using a ruler and any scale factor
identify arrows that show amplitude or wavelength on a labelled wave diagram
explain frequency as the number of waves or oscillations per second

[Maximum number: 1]
