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, |
