Light exhibits properties of both a wave and a particle. This phenomenon is known as wave-particle duality. In some experiments, light behaves like a wave, while in others, it behaves like a particle.
As a wave, light exhibits characteristics such as diffraction, interference, and polarization. It also has a wavelength and frequency, and can travel through a medium.
As a particle, light is made up of tiny packets of energy called photons. These photons have no mass and travel at the speed of light. They also have properties such as momentum and energy.
The wave-particle duality theory explains the behavior of light as both a wave and a particle. It states that depending on the type of experiment being conducted, light will exhibit properties of either a wave or a particle.
Both the wave and particle theories of light are accurate and can be used to explain different phenomena. However, the wave-particle duality theory is considered to be more accurate in describing the behavior of light.
