Wave speed - the distance the wave travels in a given amount of time
Frequency - number of events per unit of time
Period - time it takes to complete one oscillation
For Transverse Waves:
- The formula for frequency is: f (frequency) = 1 / T ; where T is the time period.
- Similarly, the formula for time is: T (period) = 1 / f
- In order to calculate the wave speed we use the formula: v = λ f where v is the speed of the wave in meters per second, λ is the wavelength in meters and f is the frequency of the wave in Hertz.
For longitudinal Waves:
- The speed of longitudinal wave is given by v=√Eρ where ρ is the density of the medium.
- Wave frequency can be measured by counting the number of compressions that pass the point in 1 second other time period.
- The period of a longitudinal wave is the time taken by the wave to move one wavelength. T = 1 / f
