Coherent and Incoherent Sources
Coherent and incoherent sources refer to the characteristics of light waves emitted by different sources.
Coherent Sources
A coherent source emits light waves with the same frequency, wavelength, and phase or with a constant phase difference. Light from a coherent source forms sustained interference patterns when the waves superimpose.
Examples of coherent sources include lasers and sound waves produced by speakers driven by electrical signals with the same frequency.

Incoherent Sources
An incoherent source emits light waves with different frequencies, wavelengths, and phases. Light from incoherent sources has frequent and random phase changes between the photons.
Examples of incoherent sources include tungsten filament lamps and ordinary fluorescent tubes emitting incoherent light.

Wave Optics
Wave optics is a branch of physics that studies various phenomena such as interference, diffraction, and polarization. It involves the behavior of light and its interaction with different mediums, leading to studying wavefronts, waves normal, coherent and incoherent sources, and other related concepts.
In this article, we will have a comprehensive study of Wave Optics, including its theories, concepts, and more.
