Answer 1

Photon energy is the energy carried by a single photon. The amount of energy is directly proportional to the photon'selectromagnetic frequency and inversely proportional to thewavelength. The higher the photon's frequency, the higher its energy. Equivalently, the longer the photon's wavelength, the lower its energy.

Answer 2

In physics, a photon is a bundle of electromagnetic energy. It is the basic unit that makes up all light. The photon is sometimes referred to as a "quantum" of electromagnetic energy. Photons are not thought to be made up of smaller particles. They are a basic unit of nature called an elementary particle.The energy of a photon is given by the equation E = hf, where E is energy, h is Planck's constant, and f is frequency. ... The wavelength of a photon depends on the frequency of radiation of the electromagnetic wave and is given by the relationship wavelength = speed of light/frequency.
