Question

What is frequency ? What is the formula ter
finding frequency ?​

Answer 1

Answer:

1) Frequency is the rate at which current changes direction per second. It is measured in hertz (Hz), an international unit of measure where 1 hertz is equal to 1 cycle per second. Hertz (Hz) = One hertz is equal to one cycle per second.

2) f = $\frac{1}{T}$

f = frequency

T = period

Answer 2

Answer:

The frequency formula in terms of time is given as: f = 1/T where, f is the frequency in hertz, and T is the time to complete one cycle in seconds. The frequency formula in terms of wavelength and wave speed is given as, f = /λ where, is the wave speed, and λ is the wavelength of the wave.
