The quantum theory of light, also known as the particle-wave duality theory, states that light can behave as both a particle (photon) and a wave. This theory was proposed by Albert Einstein in 1905, building on the work of Max Planck.
According to the theory, light is composed of discrete packets of energy called photons. These photons carry energy and momentum and exhibit particle-like properties. They have a certain wavelength and frequency, and can interact with matter in a quantized manner.
However, light also exhibits wave-like behavior. It can be described by a wave function, which undergoes interference and diffraction phenomena. The wave nature of light is observed in experiments such as the double-slit experiment, where light displays interference patterns characteristic of waves.
The energy of a photon is related to the frequency of light by Planck's constant, h. This relationship is given by the equation E = hf, where E represents the energy, h is Planck's constant, and f is the frequency of the light wave. It implies that photons with higher frequency (shorter wavelength) have higher energy.
The quantum theory of light revolutionized the understanding of the nature of light by combining wave and particle concepts. It laid the foundation for the development of quantum mechanics and has been verified by numerous experimental observations.
