Enter the speed of light and the wavelength in the calculator to determine the frequency of light.

## 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

To calculate the frequency of light, divide the speed of light by the light 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?

1. First, determine the speed of light.

The speed of light in a vacuum is 299 792 458 m / s.

2. Next, determine the wavelength.

Calculate the wavelength of the light photon.

3. Finally, calculate the frequency.

Calculate the frequency using the formula above.
