Physics notes - Waves
Units
Degree (o)
Measuring angles of incidence, reflection and refraction.
Hertz
unit of frequency, number of waves per second, can also use s ‐1
Metre
wavelength (distance between any two similar points on adjacent waves, e.g. peak to peak)
Metre/second
wave speed
Second
unit of time period (T) The time it takes for one complete
Equations
Speed = Wavelength x Frequency. V = f x λ
Frequency = 1/time period
