Watch cone cells Simple Definition
a lens with a center thicker than its edges
Watch convex lens Simple Definition
a mirror with a surface that curves outward
Watch convex mirror Simple Definition
reflection of light at many angles by a rough surface
Watch diffuse reflection Simple Definition
the transfer of energy from a wave to an object, like sound energy when it hits a wall

visible light produced when phosphor is hit by ultraviolet light
Watch fluorescent light Simple Definition
the point at which light rays converge after passing through a lens

a three-dimensional photograph created using lasers
Watch hologram Simple Definition
light produced when a metal is heated until it glows, it was used in old light bulbs
Watch incandescent light Simple Definition
a device that produces a narrow light beam of a single color and frequency
Watch laser Simple Definition
states that the angle of incidence is equal to the angle of reflection
Watch law of reflection Simple Definition
a transparent object with at least one curved surface, light bends when passing through it
Watch lens Simple Definition

Watch light Simple Definition
an instrument that uses lenses to magnify small objects
Watch microscope Simple Definition
the image of a distant object created when refracted light passes through air layers of different densities
