Physical optics is also the name of an approximation commonly used in optics, electrical engineering and applied physics. In this context, it is an intermediate method between geometric optics , which ignores wave effects, and full wave electromagnetism , which is a precise theory .

In modern physics, the double-slit experiment demonstrates that light and matter can exhibit behavior of both classical particles and classical waves.This type of experiment was first performed by Thomas Young in 1801, as a demonstration of the wave behavior of visible light. [1]
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. [1] Optics usually describes the behaviour of visible, ultraviolet, and infrared light.
Refraction of light at the interface between two media of different refractive indices, with n 2 > n 1.Since the phase velocity is lower in the second medium (v 2 < v 1), the angle of refraction θ 2 is less than the angle of incidence θ 1; that is, the ray in the higher-index medium is closer to the normal.
Consider the interference of two waves given by the form (,) = (+)(,) = (+),where the boldface indicates that the relevant quantity is a vector.The intensity of light goes as the electric field absolute square (in fact, = ‖ ‖ , where the angled brackets denote a time average), and so we just add the fields before squaring them.
In 1971, Pochi Yeh received his PhD in physics from the California Institute of Technology. He then obtained a position at Rockwell International Science Center in Thousand Oaks, California. In 1989 he became a member of the faculty at UC Santa Barbara. He is also the author and co-author of three other published books in the Optics discipline ...
Acousto-optics is a branch of physics that studies the interactions between sound waves and light waves, especially the diffraction of laser light by ultrasound (or sound in general) through an ultrasonic grating.
