What is frequency ?​

Answer 1

Answer:

Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.

Answer 2

Frequency

It is define as the number of wave pases at a fixed place in a unit interval of time.

the curve of frequency is either sine or cos wave form .

History

the word frequency come from 19th century by Heinrich Rudolf Hertz .

Mathematical term

• Frequency= Speed of light /Wavelength
• Frequency = h/Energy (where h is constant )

Some point about frequency.

• SI unit a frequency is Hertz.
• frequency is used by engineers to find number of oscillation in a wave.
