standard measure of density. Ratio of density of an object / density of water
makes rays converge at a single point

Diffraction
any bending of a wave by means other than reflection or refraction
heat transferred by electromagnetic waves: radiant energy
reflected off surface
amount of heat required to raise the temperature of 1 g of water by 1 degree C
pulse of compressed air in a longitudinal wave
Nucleus
magenta
1 cal/degree C
Central region of atom. Made of protons and neutrons
standard measure of density. Ratio of density of an object / density of water
When the speed of a fluid increases, the pressure drops
E = mc2
allow light to pass through
crests lined up with crests and troughs with troughs
Amount of rest energy E
caused by more than one vibration existing at the same time in the same space
an image that is formed by converging light rays and that can be displayed on a screen
n sinΘ = n' sinΘ'
back-and-forth vibratory motion
Snell's law
reflected off surface
how often a vibration occurs, Hz

pendulum
swings back and forth, simple harmonic motion
Specific heat of water
Central region of atom. Made of protons and neutrons
distance from midpoint to crest, maximum displacement
Light source pointed at octagonal mirror, reflects off, goes to mirror on a mountain, reflects back into eye piece. Measure amount of time to go distance. Spins the mirror until it matches up again, and then the time for mirror to go 1/8 of a turn = speed of light = 300000 km/sec
