Photon Energy Calculations and Concepts

This tutorial explains how to calculate the energy of a photon using frequency and wavelength. It covers the use of Planck's constant and the speed of light in these calculations. The tutorial also demonstrates how to calculate the energy of multiple photons using moles and Avogadro's number, and applies these concepts to photons emitted by carbon atoms.
