Nature of light

The quantum particle of light is called a photon. Light VIPer32 has both a wave-like and a particle-like nature. In other words, light can appear to be made of photons (particles) in some experiments and light can act like waves in other experiments. The dynamics of max1902 classical electromagnetic waves are completely determined by Maxwell's equations, the classical description of electrodynamics. In the absence of sources, Maxwell's equations can be written as wave equations in the electric and SI4435 magnetic field vectors. Maxwell's equations thus describe, among other things, the wave-like properties of light. When classical (coherent or thermal) light is incident on a photographic plate or CC, the average number of hits, dots, or clicks 4921QP per unit time that result is approximately proportional to the square of the electromagnetic fields of the light. By formal analogy, the wave function of a material particle can be used to find the probability density by taking its absolute-value squared. Unlike electromagnetic MC3423P1 fields, quantum-mechanical wave functions are complex. (Often in the case of ELM fields complex notation is used for convenience, but it is understood that in actual fact the fields are real. On the contrary, wave functions are genuinely complex.)
