What is a wave?
|
a disturbance that transmits energy through matter or space
|
|
|
What is a medium?
|
a substance through which a wave can travel....solid, liquid, gas
|
|
|
What are transverse waves?
|
waves in which the particles of the wave's medium vibrate perpendicularly to the direction the wave is traveling(light)
|
|
|
What are longitudinal waves?
|
a wave in which the particles of a medium vibrate back and forth along the path that the wave travels (sound)
|
|
|
What is amplitude?
|
the maximum distance a wave vibrates from its rest position
|
|
|
What is a wavelength?
|
the distance between one point on a wave and the corresponding point on an adjacent wave. (Crest to crest, trough to trough)
|
|
|
What is the frequency?
|
the number off waves produced in a given amount of time(Hertz per second)
|
|
|
What is wave speed?
|
the speed at which a wave travels
(=lamba times frequency) |
|
|
What are reflections?
|
the bouncing back of a wave as it passes at an angle from one medium to another
|
|
|
What are diffractions?
|
The bending of waves around a barrier of through an opening
|
|
|
What are refractions?
|
the bending of waves as they pass at an angle from one medium to another
|
|
|
What is interference?
|
a wave interaction that occurs when two or more waves overlap
(constructive or destructive) |
|
|
What is a standing wave?
|
a wave that forms a stationary pattern in which portions of the wave do not move and other portions move with a large amplitude
|
|
|
What is resonance?
|
what occurs when an object vibrating at or near a resonant frequency of a second object causes the second object to vibrate
|
