Wave Frequency Formula
Physics: Edexcel IGCSE, topic 3.1.4
Frequency and Period
All waves have a frequency and a period of oscillation.
Frequency
- Frequency is the number of oscillations (vibrations) per second. The frequency of a wave can be calculated as: -Frequency = 1 ÷ period
- Frequency is measured in Hertz (Hz).
Period
- The period of a wave is the time taken to complete one oscillation (vibration). The period can be calculated as:
- Period = 1 ÷ frequency
- The period of a wave is measured in seconds.
