WebOverview of X-Ray Photons. X-ray photons have large amount of energy. The energy of these photons is managed by wavelength and frequency. Wavelength is defined as the distance between two successive peaks of a wave calculated in nanometers. Frequency is defined as the number of waves passing through a given point in one second calculated in … Photon is a type of elementary particle which acts as a carrier of energy, but the electron is a subatomic particle which occurs in all the atoms. The key difference between photon and electron is that the photon is a packet of energy while the electron is a mass. Moreover, the photon does not have a rest … See more Photon is a topic that we discuss in wave mechanics. In quantum theory, we can observe that waves also have particle properties.
