PhysicsWavesGCSEAQA Created by: beckytierneyxCreated on: 02-01-17 15:09 Amplitude This is the distance between the crest (the peak of a wave) to the middle (also known as the rest position) 1 of 7 Wavelength The length of one whole wave eg. from crest to crest. 2 of 7 Frequency The number of waves per second, it's measured in Hertz (Hz) 3 of 7 Transverse Waves The vibrations are PERPENDICULAR to the DIRECTION OF ENERGY TRANSFER. The vibrations go from side to side. 4 of 7 Examples of Transverse Waves Light, any wave on the EM spectrum, tidal waves. 5 of 7 Longitudinal Waves The vibrations are PARALLEL to the DIRECTION OF ENERGY TRANSFER. The vibrations go in the same direction as the energy. 6 of 7 Examples of Longitudinal Waves Sound waves, ultrasound, shock waves (Seismic waves) 7 of 7
