Terms in this set (23)
a material that transmits light without scattering; light passes right through it
allows some light to pass through it, but scatters the light in many directions
A material that reflects or absorbs all of the light that strikes it.
three colours (red, green and blue) that can be combined to produce all the other colours
colours that are produced by combining the three primary colours
A straight line used to represent a light wave.
Reflection that occurs when parallel rays of light hit a smooth surface and all reflect at the same angle e.g. from a mirror.
Reflection that occurs when parallel rays of light hit a rough surface and all reflect at different angles e.g. from a piece of paper.
A flat mirror.
A copy of an object formed by reflected or refracted rays of light.
A mirror with a surface that curves inward.
A mirror with a surface that curves outward.
Refraction is the bending of light rays whenever light passes from one transparent substance to another, due to it changing speed.
The point at which light rays meet, or appear to meet, after being reflected (or refracted) by a mirror (or a lens).
A curved piece of glass or other transparent material that is used to refract light.
A lens that is thicker in the center than at the edges.
A lens that is thinner in the center than at the edges.
The opening in the center of the iris through which light enters the inside of the eye.
Located at the very back of the eyeball, is a thin film that contains cells that are extremely sensitive to light.
When a person can see nearby objects clearly but cannot bring distant objects into focus
When a person can see distant objects clearly but cannot bring nearby objects into focus
A device that produces a narrow beam of light.
A long, thin strand of glass or plastic that can carry light for long distances without allowing the light to escape.
