Wave Properties
A wave transfers energy from one place to another without transferring matter. Waves are described by their wavelength, frequency, and amplitude.
Key measurements
Wavelength is the distance between one point on a wave and the same point on the next wave. Frequency is how many waves pass a point per second, measured in hertz (Hz). Amplitude is the maximum height of the wave from its resting position.
The wave equation
Wave speed = frequency × wavelength. If you know two of these values, you can calculate the third.
Practice
A wave has a frequency of 5Hz and a wavelength of 2m. What's its speed?
