Question

How to represent frequency? Also, what is the definition of frequency?

Answer 1

Definition of frequency:

1. Frequency is defined as the number of total waves or number of vibrations produced in one second.
2. Frequency, $\nu =\frac{1}{T}$.

Representation of frequency:

1. Frequency is a parameter of the wave. Frequency is represented by $\nu$.
2. Frequency, $v=\frac{c}{\lambda }$, where $c$ and $\lambda$ are the velocity of light and wavelength respectively.
3. Again, frequency, $\nu =\frac{1}{T}$, where T is the time period of any wave.
4. Frequency is inversely proportional to wavelength. If wavelength increases, then the frequency will decrease, i.e, the number of complete waves will decrease.
