Longitudinal and Transverse 2 of 12 What is the difference between a longitudinal wave and a transverse wave? The oscillation 3 of 12 Give a definition of transverse waves? The oscillation is at 90* to the direction of motion. 4 of 12 Give a definition of longitudinal waves? The oscillation is along the direction of motion. 5 of 12 Give 2 examples of transverse waves? -Light and all electromagnetic spectrum waves -Ripples on water -Waves on strings 6 of 12 Give two examples of longitudinal waves? -Sound waves -Shock waves 7 of 12 What is wavelength? The wavelength is the length of one complete wave. 8 of 12 What is wavelength measured in? Wavelength is measured in meters and has the symbol lamda. 9 of 12 What is frequency? The frequency of a wave is counted as the number of waves that pass a point per second. 10 of 12 What is frequency measured in? Frequency is measured in Hertz (Hz). 11 of 12 What does amplitude mean? The height of the wave, more correctly the maximum displacement of a particle from it's rest position. 12 of 12
