Record number: 1, Textual support number: 1 CONT

Ray-tracing technique relies on an extremely time-consuming algorithm to compute the reflection and refraction of light from the surfaces of imaginary objects. Basically the computer program traces individual light rays, starting at the viewpoint and passing backward through each pixel in the image plane until the ray hits a surface. The reflected ray is then continued to see if it could have come from a light source, either directly or after reflection from another object. For a transparent surface a second, refracted ray must also be traced.  7, record 1, English, - ray%20tracing

Magneto-optics is the study of effects arising from the interaction of light with magnetized media. Initially linearly polarized light, after interaction with such materials, can exhibit both ellipticity and a rotation of the polarization state. These effects are generally categorized into two phenomena, the Faraday Effect which occurs when electro-magnetic radiation is transmitted through a magnetized media, and the Kerr Effect which deals with reflections from the magnetized media. The Magneto-Optical Kerr Effect(MOKE) is further categorized by the direction of the magnetization vector with respect to the reflection surface and the plane of incidence... If the magnetization vector is perpendicular to the reflection surface and parallel to the plane of incidence, the effect is called the polar Kerr effect. As a matter of simplification, near normal incidence is usually employed when doing experiments in the polar geometry. In the longitudinal effect the magnetization vector is parallel to both the reflection surface and the plane of incidence. When the magnetization is perpendicular to the plane of incidence and parallel to the surface it is said to be in the transverse configuration.  2, record 8, English, - Magneto%2DOptical%20Kerr%20Effect

Magneto-optic Kerr effect(MOKE) is one of the magneto-optic effects. It describes changes of the reflections from the magnetized media. It is similar to the Faraday effect that describes the light passing through the media. The light that is reflected from a magnetized surface, changes in polarization. MOKE can be further categorized by the direction of the magnetization vector with respect to the reflection surface and the plane of incidence. When the magnetization vector is perpendicular to the reflection surface and parallel to the plane of incidence, the effect is called the polar Kerr effect.  2, record 10, English, - polar%20Kerr%20effect

Specular reflection is described by the law of reflection, according to which incident and reflected waves lie in the plane of incidence, defined by the normal to the interface and the direction of the incident wave, and make the same angle of incidence with this normal. Specular reflection is distinguished from refraction in that the direction of propagation of the reflected wave has a component opposite the direction of the incident wave.
