How to Calculate the Energy of a Photon of Light?

When determining the energy of a photon of light, it is essential to understand the formula E = hf. In this formula, E represents the energy of the photon in joules, h is the Planck's constant (6.626 × 10^-34 Js), and f stands for the frequency of the photon in hertz.

To calculate the energy of a photon of light, you simply need to multiply the frequency of the photon by Planck's constant. The resulting value will give you the energy of the photon in joules.

For example, if you have a photon with a frequency of 6.17 x 10^14 Hz, you can calculate its energy as follows:

E = 6.17 x 10^14 Hz x 6.626 x 10^-34 Js = 4.088 x 10^-19 J

Therefore, the energy of a photon of light with a frequency of 6.17 x 10^14 Hz is 4.088 x 10^-19 joules.
