Science - Chp. 6 Light

Front 1

bioluminescence

Back 1

light produced by living organisms

Front 2

laser

Back 2

a device that produces a thin stream of light of just a few close wavelengths

Front 3

concave lens

Back 3

a lens that curves inward (is thicker at the edges than at the middle) and spreads light rays apart

Front 4

primary color

Back 4

red, green, or blue; mixing these colors can produce all the colors of the spectrum

Front 5

prism

Back 5

a cut piece of clear glass (or plastic) with two opposite sides in the shape of a triangle or other geometric shape

Front 6

electromagnetic spectrum

Back 6

all the wavelengths of visible and invisible light in order from short (gamma rays) to long (radio)

Front 7

electromagnetism

Back 7

the production of magnetism by electricity and the production of electricity by magnets

Front 8

primary pigment

Back 8

magenta, cyan, yellow; material with any of these colors absorbs one primary color of light and reflects the other two

Front 9

light ray

Back 9

a straight-line beam of light as it travels outward from its source

Front 10

law of reflection

Back 10

the angle of the angle of
an incoming = the
light reflected ray

(equals)

Front 11

convex lens

Back 11

a lens that curves outward
(is thicker at the middle than at the edges) and brings light rays together

Front 12

spectrum

Back 12

a band of colors produced when light goes through a prism

Front 13

refraction

Back 13

the bending of light rays as they pass from one substance into another

Front 14

transparent

Back 14

letting all light through,

so that objects on the other side can be seen clearly

Front 15

convex mirror

Back 15

a mirror that curves out on the shiny side

Front 16

concave mirror

Back 16

a mirror that curves in on the shiny side

Front 17

opaque

Back 17

completely blocking light from passing through

Front 18

polarization

Back 18

allowing light vibrations to pass through in only one direction
