For instance, seismic waves carry energy from the ... the two simplest types of wave interactions with rocks: reflection and refraction. Ask students to define reflection. They should be able ...

Optical density and index of refraction are defined and related to reflection and refraction. The concept of refraction is used to explain mirages. Students use mirror equations to determine the ...

Reflection and refraction occur whenever light encounters a material at an angle, because one side of the beam is able to race ahead of the other. As a result, the wavefront changes direction.

Refraction close refractionProcess by which ... Put an arrow on it to show its direction. The law of reflection states that: angle of incidence i = angle of reflection r. For example, if a light ...

The reflection of light rays is one of the major aspects of geometric optics; the other is refraction, or the bending of light rays. Geometric optics is one of two broad classes of optics ...
