WAVES 0.0 / 5 ? PhysicsWavesASAQA Created by: aspanuCreated on: 27-04-16 20:59 DISPLACEMENT is the distance moved by the particle from its equilibrium position. 1 of 9 AMPLITUDE is the maximum displacement of the particle from its equilibrium position. 2 of 9 WAVELENGTH is the distance between 2 successive points on a wave which are in phase with one another. 3 of 9 PERIOD is the time taken for a particle on the wave to complete one oscillation. 4 of 9 FREQUENCY is the number of complete oscillations that pass through a given point in 1 second. (Units: Hertz(Hz) or s-1) 5 of 9 COMPRESSION is a region where particles are close to one another. (High pressure) 6 of 9 RAREFACTION is a region where the particles are further apart. (Low pressure) 7 of 9 PHASE DIFFERENCE (φ) between two particles or two waves tells us how much a particle (or wave) is in front or behind another particle (or wave). 8 of 9 INTENSITY is the rate of transfer of energy per unit area perpendicular to the direction of travel of the wave. 9 of 9
