Question

Define what is frequency

Answer 1

• As we know that a number of periods or regularly occurring events of any given kind in unit of time is known as frequency.

• We know that unit of frequency is hertz.

• The one hertz is the same as one cycle per second.

• The formula of frequency is  $f = 1/T$ , where f is frequency and the T is period.

Answer 2

• When the same event repeats per unit time, the number of occurrences of that event is called frequency.
• Frequency is measured in hertz (Hz).
• Hertz (Hz) is equal to one event per second.
• The period is reciprocal of the frequency.
• Frequency is used to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light.
