wave frequency

Wave frequency refers to how many waves pass a specific point in one second. It's measured in hertz (Hz). For example, if 60 waves pass by each second, the wave’s frequency is 60 Hz. Higher frequency means more waves are passing in the same time, which often results in higher pitch in sound waves or more energy in light waves. Conversely, lower frequency means fewer waves per second, seen in lower-pitched sounds or longer-wavelength light. Frequency helps describe the behavior of waves, influencing how we perceive sound, light, and other forms of energy.
