Frequency

Frequency is a measure of how often a specific event occurs in a given period of time. In the context of science and physics, frequency is often used to describe the number of oscillations or vibrations of a wave in a given amount of time.

Understanding Frequency

In simple terms, frequency refers to the number of cycles of a wave that occur in a unit of time. For example, in the case of sound waves, frequency is perceived as pitch - higher frequency corresponds to a higher pitch, and lower frequency corresponds to a lower pitch.

Measuring Frequency

The unit of measurement for frequency is hertz (Hz), which represents one cycle per second. So, if a wave completes 10 full cycles in one second, its frequency is 10 Hz.

Calculating Frequency

The formula to calculate frequency is:

Frequency (f) = 1 / Time period (T)

Where time period is the time taken for one complete cycle of the wave.
