Answer 1

A photon is a quantum of EM radiation. Its energy is given by E = hf and is related to the frequency f and wavelength λ of the radiation by

E=hf=hcλ(energy of a photon)E=hf=hcλ(energy of a photon),

where E is the energy of a single photon and c is the speed of light. When working with small systems, energy in eV is often useful.
