Ripples travel across the surface of water in a shallow tray and pass a small floating bead. In a second demonstration, sound travels through air from a loudspeaker to a microphone.
Describe what happens in these two demonstrations.
Your answer should include:
112 exam-style questions on Edexcel GCSE Physics 4.1 Wave properties, covering 4.1.1 Waves transfer energy and information, 4.1.2 Frequency, wavelength, amplitude, period and wavefronts, 4.1.3 Longitudinal and transverse waves, 4.1.4 The wave speed equations, 4.1.5 Measuring wave velocity, and 4.1.6 Calculating depth or distance from waves. Each one has a worked solution and a mark scheme showing where the marks go.
