A law that states that the angle of incidence and the angle of reflection are equal to eachother. | law of reflection |
A light wave that strikes a boundary and its path is drawn as a straight line arrow | incident ray |
drawn as a dashed line and at a 90 degree angle to the point where the incident ray strikes the barrier | normal |
(blank) jirrors produce only virtual images | plane |
upright images in mirrors that seem to be in or behind the mirror | virtual image |
inverted imgaes that are formed by convergerging light rays and can be displayed on a screen. | real images |
the study of reflective properties of surfaces | acoustics |
a bending of a wave as it crosses the boundary between two media at an angle | refraction |
bouncing back of a particle or wave that strikes a boundary between two media | reflefction |
angle betweent he reflected ray and the normal | angle of reflection |
A metal surface is (blank) to light waves that shine upon it. | Rigid |
when is a wave totally refelcted? | it reaches a rigid boundary |
