What is wave frequency?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Wave frequency is the number of complete wave cycles that pass a fixed point per second. For any wave sound, light, water, or electromagnetic frequency determines key properties:
- Sound waves: Frequency determines pitch (high frequency = high pitch)
- Light waves: Frequency determines color (violet highest, red lowest in visible spectrum)
- Radio waves: Frequency determines the broadcast channel
Higher frequency means more energy and shorter wavelength.
