Terms
undefined, object

- bioluminescence
- light produced by living organisms
- laser
- a device that produces a thin stream of light of just a few close wavelengths
- concave lens
- a lens that curves inward (is thicker at the edges than at the middle) and spreads light rays apart
- primary color
- red, green, or blue; mixing these colors can produce all the colors of the spectrum
- prism
- a cut piece of clear glass (or plastic) with two opposite sides in the shape of a triangle or other geometric shape
- electromagnetic spectrum
- all the wavelengths of visible and invisible light in order from short (gamma rays) to long (radio)
- electromagnetism
- the production of magnetism by electricity and the production of electricity by magnets
- primary pigment
- magenta, cyan, yellow; material with any of these colors absorbs one primary color of light and reflects the other two
- light ray
- a straight-line beam of light as it travels outward from its source
- law of reflection
-
the angle of the angle of
an incoming = the
light reflected ray
(equals) - convex lens
-
a lens that curves outward
(is thicker at the middle than at the edges) and brings light rays together - spectrum
- a band of colors produced when light goes through a prism
- refraction
- the bending of light rays as they pass from one substance into another
- transparent
-
letting all light through,
so that objects on the other side can be seen clearly - convex mirror
- a mirror that curves out on the shiny side
- concave mirror
- a mirror that curves in on the shiny side
- opaque
- completely blocking light from passing through
- polarization
- allowing light vibrations to pass through in only one direction
