Chapter 13: Light 

________: a technique that produces a hologram- a complete three- dimensional photographic image of an object.

________ result when the air at ground level is much warmer or cooler than the air above it.

________: transmit almost all the light striking them, so you can see objects clearly through them.

________: an image of a distant object produced by the refraction of light through air layers of different densities.

________ makes light transmission in optical fibers possible.

A(n) ________ is a device that reads intensities of reflected light and converts the information to digital signals.

________ causes a prism to separate a beam of white light into different colors.

________: a colored material that is used to change the color of other substances.

________ is an inherited sex- linked condition in which certain cones do not function properly.

________: generated by heating a piece of metal until it glows.

________ is produced when the three primary col- ors of light are mixed.

Inside a(n) ________ is a tube that contains a mixture of neon gas, a small amount of argon gas, and a small amount of sodium metal.

A(n) ________ is bent away from the normal as it passes from water to air.

________ is caused by a change in the speed of a wave when it passes from one material to another.

Illuminating objects with ________ produces holograms.

________: occurs when light traveling from one medium to another is completely reflected at the boundary between the two materials.

________ also are used to explore the inside of the human body.

only absorbs and reflects light-no light passes through it

allow some light to pass through them

transmit almost all the light striking them, so you can see objects clearly through them

a property of the material that indicates how much the speed of light in the material is reduced

generated by heating a piece of metal until it glows

uses phosphors to convert ultraviolet radiation to visible light

light of only one wavelength that travels with its crests and troughs aligned

can contain more than one wavelength, and its electromagnetic waves are not aligned

the waves vibrate in only one direction
