## Frequency of Light Formula

The following equation can be used to calculate the frequency of light.

f = c/w

- Where f is the frequency
- c is the speed of light
- w is the wavelength

## Frequency of Light Definition

The frequency of light is defined as the inverse of the total time it takes light to travel one wavelength.

## Frequency of Light Example

How to calculate the frequency of light?

**First, determine the speed of light.**The speed of light in a vacuum is 299 792 458 m / s.

**Next, determine the wavelength.**Calculate the wavelength of the light photon.

**Finally, calculate the frequency.**Calculate the frequency using the formula above.
