Wave Basics 0.0 / 5 ? PhysicsWavesGCSEAQA Created by: kennedylilyCreated on: 23-12-15 12:35 What is the amplitude? The amplitude is the displacement from the rest position to the crest (top of a wave) 1 of 11 What is the wavelength? The wavelength is the length of a full cycle of the wave ( e.g. from crest to crest) 2 of 11 What is the frequency? The frequency is the number of complete waves passing a certain point per second OR the number of waves produced from a source each second 3 of 11 What is frequency measured in? Frequency is measured in hertz (Hz). 1 hertz is 1 wave per second 4 of 11 Which direction are the vibrations in transverse waves? In transverse waves, the vibrations are perpendicular to the direction of energy transfer of the wave 5 of 11 Which direction are the vibrations in longitudinal waves? In longitudinal waves, the vibrations are parallel to the direction of energy transfer of the wave 6 of 11 What are some examples of transverse waves? 1. Light and all EM waves 2. Ripples on water 7 of 11 What are some examples of longitudinal waves? 1. Sound waves and ultrasound 2. Shock waves (e.g. seismic waves) 8 of 11 Which type of wave has evenly spaced vibrations? Transverse waves 9 of 11 Which type of wave has compressions and rarefactions? Longitudinal waves 10 of 11 What is the formula for wave speed? speed (m/s) = frequency (Hz) x wavelength (m) 11 of 11
