Frequency: The number of complete oscillations or wave cycles per unit time.
Explanation
Frequency is measured in hertz (Hz), where one hertz means one cycle per second. Higher frequency means more cycles occur per second. Sound frequency determines pitch, with higher frequencies producing higher-pitched sounds. Light frequency determines color, with different colors having different frequencies. Radio waves, microwaves, and X-rays are all electromagnetic waves with different frequencies.
Example
A tuning fork vibrating 440 times per second has a frequency of 440 Hz and produces the musical note A.
