Web14 dec. 2024 · The half value layer expresses the thickness of absorbing material needed for reduction of the incident radiation intensity by a factor of two. Half Value Layer – X … WebThe amount of energy is directly proportional to the photon's electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon's frequency, the higher its energy. Equivalently, the longer the photon's wavelength, the lower its energy. Photon energy can be expressed using any unit of energy.
