A series of free GCSE/IGCSE Physics Notes and Lessons.
The following diagrams show the properties of waves: amplitude and wavelength.
Describe wave motion in terms of amplitude, wavelength, frequency and period.
The Wave Equation
How to use the wave equation to calculate the speed of a wave?
Describe a method for measuring the speed of sound waves in air.
Velocity = frequency × wavelength
v = f × λ
Example:
1. A wave has a frequency of 165 Hz and a wave length of 2 m. Calculate the speed of the wave.
2. A wave has a frequency of 10000 Hz and a wave length of 2 cm. Calculate the speed of the wave.
3. A wave has a speed of 500 m/s and a frequency of 200 Hz. Calculate the wavelength.
