Types and Properties of Waves Quiz

Longitudinal = Oscillations parallel to the direction of energy transfer Transverse = Oscillations perpendicular to the direction of energy transfer Sound wave = Example of a longitudinal wave Light wave = Example of a transverse wave

Frequency = Number of waves that pass a point each second Period = Length of time for one wave to pass a given point Wavelength = Distance from one point on a wave to the identical point on the next wave Amplitude = Maximum distance of a point on the wave from its rest position

Reflection = When light bounces back at a boundary between materials Refraction = When light changes speed and bends as it moves from one medium to another Peak = Highest point of the wave Trough = Lowest point of the wave
