Frequency refers to how often the wave oscillates or completes a cycle in one second.
It is measured in Hertz (Hz), where one Hertz equals one cycle per second.
From the angular frequency provided in the wave equation, , you can determine the frequency using the formula:
For this example, the frequency is approximately .
Frequency is inversely related to the period of the wave, which is the time taken to complete one cycle.
- Higher frequencies imply shorter periods and vice versa.
A higher frequency indicates more cycles per unit time, which means more energy in the wave.
