Card Set Information
SHM and waves
What is wavelength?
Distance between any two consecutive identical points along a wave; distance interval for wave repitition.
what is amplitude?
1/2 of crest to trough distance.
maximum displacement for equilibrium on either side.
What is a crest?
Point of maximum positive displacement. a+ peak.
what is a trough?
a maximum negative displacement; a - peak
what is Equilibrium?
Point (or line) of Zero displacement; undisturbed position.
What is a Cycle?
One complete vibration or Oscillation.
The distance measured from crest to crest.
What is a Period?
The time it takes for one wave to repeat itself.
Time / # of Cycles
What is Frequency?
# of Cycles/ time
A moving distrubance requiring a material medium to move in it is called
A wave in whcih the medium vibrates parallel to the direction of wave travel is a
As a mechanical wave travels, it transfers an amount of------ related to the waves amplitude.
Frequency has a SI unit of
Hz (or s
What does SHM stand for?
Simple Harmonic Motion
At a constant speed, if the wavelength increases, then the frequency of the wave must
if the wavelength increases, then the speed of the wave must...
the relationship between wavelenth and frequency is a(n)
The speed of an mechanical wave can be varied only by changing the
If a wave propigates at one cycle every 1 second, then it has a ____ of 1s.
Period is defined as
time for one cycle
This is not an example of SHM
a record rotation on a turntable..
this is an example of SHM
a child swinging on a swing.
amplitude is defined as the
maximum displacement from equilibrium
For SHM where do the force and acceleration have maximum magnitude?
At the crest and the trough of a wave.
For SHM where does maximum velocity occur?
