|
law of reflection
|
the angle of reflection is equal to the angle of incedence
|
|
|
angle of incidence
|
the angle of the incoming wave and the imaginary perendicular wave

|
|
|
2 types of interference
|
constructive and destructive
|
|
|
constructive interference
|
when two waves combine to make a wave w/ a larger amplitude (builds up a wave)
|
|
|
destructive interference
|
when the amplitude of two waves combine with each other producing a smaller amplitude (destroys a wave)
|
|
|
standing waves
|
a wave that appears to be standing in one place even though it is actually 2 waves interfering as they pass through each other
|
|
|
node
|
when destructive interference causes two waves to combine and produce an amplitude of 0
|
|
|
antinode
|
the crest and trough of the standing wave. these are the points of maximum energy
|
|
|
an earthquake occurs when
|
rocks beneath the earth's surface move
|
|
|
seismic waves
|
the waves created by the movement of th rocs beneath the earths surface
|
|
|
3 types of seismic waves
|
primary
secondary surface |
|
|
tsunami
|
huge waves formed by underwater earthquakes
|
|
|
primary waves
|
they are all called primary waves because they move faster than othe rseismic waves p-waves
|
|
|
