Waves key definitions
Cards in this deck (8)
- 1CoherentTwo sources are coherent if they have the same wavelength and frequency and a fixed phase difference between them
- 2WaveTransfers energy from one point to another, e.g. EM waves causing things to heat uo
- 3Displacement, X, metresHow far a wave has moved from its undisturbed position
- 4Amplitude, a, mMaximum displacement
- 5Wavelength, lambda, mThe length of one wave from crest to crest or trough to trough
- 6Period, T, secondsThe time taken for a whole vibration
- 7Frequency, f, hertzThe number of vibrations per second passing a given point
- 8Phase differenceThe amount by which one wave lags behind another wave. Measured in degrees or radians
