Waves
waves
word | definition |
---|---|
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, |
