24 Waves, Sound & Light

wave a disturbance that moves through matter or space
transverse wave a mechanical wave that causes particles in matter to move back and forth at right angles to the direction in which the wave travels
compressional wave a mechanical wave that causes particles in matter to move back and forth along the same direction in which the wave travels
wavelength the distance between a point on a wave and the nearest point moving with the same speed and direction
frequency the number of wavelengths that pass by a point each second
law of reflection the angle that the incoming wave makes with the normal equals the angle that the outgoing wave makes with the normal
refraction the change in direction of a wave when it changes speed as it travels from one material to another
diffraction the bending of waves around an object
intensity the amount of energy that a wave carries past a certain area each second
pitch the human perception of the frequency of sound (how high or high low a sound is)
reverberation repeated echoes
electromagnetic waves waves that can travel through natter or through empty space
electromagnetic spectrum the complete range of electromagmetic wave frequencies and wavelengths
infrared waves have wavelengths between .001 meters and 700 billionths of a meter
ultraviolet waves have wavelengths between 400 billionths and 10 billionths of a meter
spectrum a range of values or properties
perception a recognition, sense, or understanding of something
density the mass per cubic meter of a substance
