When a wave strikes an object and bounces off
|
reflection
|
|
|
Repeating disturbances that transfer energy through matter or space
|
waves
|
|
|
Highest point of a transverse wave
|
crest
|
|
|
Region where the medium is crowded and dense in a compressional (squeezed) wave
|
compression
|
|
|
A wave that makes matter in the medium move back and forth (perpendicular)at right angles to the directin the wave travels
|
transverse wave
|
|
|
Ability of two or more waves to combine and form a new wave
|
interference
|
|
|
Lowest point of a transverse wave
|
trough
|
|
|
Material through which a wave transfers energy
|
medium
|
|
|
The bending of waves around a barrier
|
diffraction
|
|
|
Less dense region of a compressional wave (spread out)
|
rarefaction
|
|
|
Ability of an object to vibrate by absorbing energy at its natural frequency
|
resonance
|
|
|
Wave in which matter in the (squeeze and let go spring)medium moves back and forth in the same direction the wave travels
|
compressional wave
|
|
|
Distance between one point in a wave and the nearest (trough to trough) point just like it
|
wavelength
|
|
|
Measure of how many wavelengths pass a fixed point each second
|
frequency
|
|
|
The angle of incidence is equal to the angle of reflection
|
law of reflection
|
|
|
Measure of the energy in a wave
|
amplitude
|
|
|
A special type of wave pattern that forms when waves of equal wave length and amplitude traveling in opposite directions continuously interfere with each other
|
standing wave (violin)
|
|
|
The bending of a wave caused by a change in its speed as it moves from one medium to another
|
refraction
|
|
|
Why do surfers like water waves with high amplitudes?
|
more energy
