Bell Ringer: How are waves and energy related?
Finish transverse / longitudinal activity
Finish 15.1 notes
Anatomy of a wave
Node - the part of a wave at equilibrium
Antinode - the part of a wave furthest from equilibrium
Crest - high point of a wave
Trough - low point of a wave
Wavelength - the distance between two identical parts of a wave
Frequency - the number of waves that go by a point each second
Period - the time for one complete cycle of a wave to go by
Amplitude - the distance from equilibrium to the antinode of a wave
Wave speed
wave speed = frequency x wavelength
wave speed = distance / time
