Equation of Wave

In I/GCSE Physics, The **distance travelled by a wave **can be worked out using the formula:

**Distance (metres) = Wave speed (metres per second m/s) x Time (seconds)**

All **waves **have several important features:

**Amplitude**– The maximum disturbance caused by a wave. It is measured by the distance from a crest or trough of the wave to the undisturbed position.**Wavelength**– The distance between corresponding points on two adjacent cycles.**Frequency**– the number of waves produced in one second. Frequency is measured in**hertz**(**Hz**).

Wave speed, frequency and wavelength are related by the following formula:

**Wave speed (metres per second, m/s) = Frequency (hertz, Hz) x Wavelength (metres, m)**

For a constant wave speed, the wavelength is **INVERSELY PROPORTIONAL **to the frequency in the syllabus of I/GCSE Physics.

That's all for today! Great!
