# Calculate the energy of a photon with a wavelength of 565 nm

## How can we calculate the energy of a photon with a wavelength of 565 nm?

What is the equation to calculate the energy of a photon?

## Calculating the energy of a photon with a wavelength of 565 nm

To calculate the energy of a photon with a specific wavelength, we can use the equation E = hc/λ.

When calculating the energy of a photon with a wavelength of 565 nm, we use the equation E = hc/λ.

Given that the wavelength of the photon is 565 nm, we convert it to meters by dividing by 10^9:

λ = 565 nm = 565 x 10^-9 m

Substitute the values into the equation:

E = (6.626 x 10^-34 J·s) x (3.00 x 10^8 m/s) / (565 x 10^-9 m)

Simplify the equation to find the energy of the photon:

**E = 3.71 x 10^-19 J**
