QuestionAnswer
the bouncing back of a particle or wave that srikes the boundary between two media. reflection
a line perpendicular to a surface normal
angle between an incident ray and the normal to a surface angle of incidence
angle between a reflected ray and the normal to a surface angle of reflection
the angle of incidence for a wave that strikes the surface is equl to the angle of reflection. This is true for both partially ad totally reflected waves. law of reflection
the reflection of waves in many directions from a rough surface. diffuse reflection
an image formed though reflection or rarefraction that can be seen by an observer but cannot be projected on a screen because light from the object does not actually come to focus. virtual image
persistance of a sound, as in an echo, due to multiple reflections reverbation
the change in direction of a wave as it crossses the boundary between two media in which the wave travels at different speeds. refraction
the crest, trough, or any continuous portion of a 2D or 3D wave in which the vibrations are all the same way at the same time wave front
the floating image that appears in the distance and is due to the refraction of light in Earth's atmosphere mirage
the seperation of light into colors arranged according to their frequency, by the interaction with a prism or defration grading, for example dispersion
the minimum angle of incidence for which the light ray is totally reflected in the medium critical angle
the 100% reflection(with no transmition) of light that strikes a boundry between two media at an angle greater than the critical angle total internal reflection
a transparent fiber, usually of glass or plastic that can transmit light down it's length by means of total internal reflection optical fiber
