Define the amplitude of a wave - Answer The distance from the rest position to the top of the wave Define the period of a wave - Answer The time taken for one wavelength to pass a point Define the frequency of a wave - Answer The number of waves per second How many ms are in 1s? - Answer 1000 Define coherent light - Answer Coherent light has the same frequency/wavelength and is in phase Define a transverse wave - Answer The oscillations are perpendicular to the direction of travel Define a longitudinal wave - Answer The oscillations are parallel to the direction of travel How many radians are in 360 degrees? - Answer 2 pi Define phase difference - Answer Phase difference shows how much two waves are in line with each other. Measured in fractions or degrees What is constructive interference? - Answer When two waves in phase add together to make a larger amplitude wave What is destructive interference? - Answer When two waves in antiphase cancel each other out
