In specular reflection, the direction of the reflected ray is determined by the angle the incident ray makes with the surface normal, a line perpendicular to the surface at the point where the ray hits.

The incident and reflected rays and the normal lie in a single plane, and the angle between the reflected ray and the surface normal is the same as that between the incident ray and the normal.

In general, as the refractive index exceeds a number, where is a natural number, the critical incidence angle for times internally reflected rays escapes the domain [ 0, \ frac { \ pi } { 2 } ].

It is also possible to produce polarized light rays using a combination of reflection and refraction : When a refracted ray and the reflected ray form a right angle, the reflected ray has the property of " plane polarization ".

The second ray or the reflected ray is done in a similar way to the first ray, but in this case it adds the heights of the antennas for form the right triangle by the reflection of the height of the transmitter.

When the long axis of the mirror, the missile axis and the line of sight to the target all fell in the same plane, the reflected rays from the target reached the detector ( provided the target was not very far off axis ).

The only part of the forward scattering hemisphere that does not receive a reflected ray is the shadow of the sphere . ( And, in Mie theory, even this isn't true due to diffraction around the edge of the sphere . )-- Fuzzyeric 13 : 17, 18 September 2006 ( UTC)

For simplicity, " reflections " are spoken of here, but more generally the interface between the small particles that constitute many materials is irregular on a scale comparable with light wavelength, so diffuse light is generated at each interface, rather than a single reflected ray, but the story can be told the same way.
