In specular reflection the phase of the reflected waves depends on the choice of the origin of coordinates, but the relative phase between s and p TE and TM polarizations is fixed by the properties of the media and of the interface between them. Reflection is enhanced in metals by suppression of wave propagation beyond their skin depths.

Reflection also occurs at the surface Xample of a reflective account from transparent media, such as water or glass.

Diagram of specular reflection In the diagram, a light ray PO strikes a vertical mirror at point O, and the reflected ray is OQ. In fact, reflection of light may occur whenever light travels from a medium of a given refractive index into a medium with a different refractive index.

In the most general case, a certain fraction of the light is reflected from the interface, and the remainder is refracted. Solving Maxwell's equations for a light ray striking a boundary allows the derivation of the Fresnel equationswhich can be used to predict how much of the light is reflected, and how much is refracted in a given situation.

This is analogous to the way impedance mismatch in an electric circuit causes reflection of signals.

Total internal reflection of light from a denser medium occurs if the angle of incidence is greater than the critical angle. Total internal reflection is used as a means of focusing waves that cannot effectively be reflected by common means.

X-ray telescopes are constructed by creating a converging "tunnel" for the waves. As the waves interact at low angle with the surface of this tunnel they are reflected toward the focus point or toward another interaction with the tunnel surface, eventually being directed to the detector at the focus.

A conventional reflector would be useless as the X-rays would simply pass through the intended reflector.

When light reflects off a material denser with higher refractive index than the external medium, it undergoes a phase inversion. In contrast, a less dense, lower refractive index material will reflect light in phase. This is an important principle in the field of thin-film optics. Specular reflection forms images.

Reflection from a flat surface forms a mirror imagewhich appears to be reversed from left to right because we compare the image we see to what we would see if we were rotated into the position of the image.

Specular reflection at a curved surface forms an image which may be magnified or demagnified; curved mirrors have optical power. Such mirrors may have surfaces that are spherical or parabolic. Refraction of light at the interface between two media.

Laws of reflection Main article: Specular reflection If the reflecting surface is very smooth, the reflection of light that occurs is called specular or regular reflection.

The laws of reflection are as follows: The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane. The angle which the incident ray makes with the normal is equal to the angle which the reflected ray makes to the same normal. The reflected ray and the incident ray are on the opposite sides of the normal.

These three laws can all be derived from the Fresnel equations. Mechanism Play media 2D simulation: White blur represents the probability distribution of finding a particle in a given place if measured.

In classical electrodynamicslight is considered as an electromagnetic wave, which is described by Maxwell's equations. Light waves incident on a material induce small oscillations of polarisation in the individual atoms or oscillation of electrons, in metalscausing each particle to radiate a small secondary wave in all directions, like a dipole antenna.

All these waves add up to give specular reflection and refraction, according to the Huygens—Fresnel principle. In the case of dielectrics such as glass, the electric field of the light acts on the electrons in the material, and the moving electrons generate fields and become new radiators.

The refracted light in the glass is the combination of the forward radiation of the electrons and the incident light.

The reflected light is the combination of the backward radiation of all of the electrons. In metals, electrons with no binding energy are called free electrons. Light—matter interaction in terms of photons is a topic of quantum electrodynamicsand is described in detail by Richard Feynman in his popular book QED: The Strange Theory of Light and Matter.

Diffuse reflection Main article: Diffuse reflection When light strikes the surface of a non-metallic material it bounces off in all directions due to multiple reflections by the microscopic irregularities inside the material e.
