wave is a disturbance that moves though matter or space
transverse wave causes particles in matter to move back and forth at right angles to the direction in which the wave travels
compressional wave causes particles in matter to move back and forth along the same direction in which the wave travels
wavelength the distance between one point on a wave and the nearest point moving with the same speed and direction
frequency is the number of wavelength 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 is the change in direction of a wave when it changes speed as it travels from one material to another
diffraction which is the bending of waves around an object
opaque not able to see through
translucent allowing light, but not detailed images, to pass through; semitransparent.
transparent see through
reflect bounces off
absorb take in or soak up
transmit lets light go through
loudness the volume of the wave
pitch the low or the high of a wave
echolocation the location of objects by reflected sound
echo when sound bounces of an object
doppler effect an increase or decrease in the frequency of sound,
