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!
