Wave definition
transport of energy without moving anything
oscilation definition
movement in a regular rhythm.
Period definition?
time for one whole cycle of an oscilation
Frequency definition?
number of whole cycles occurring in a second
Displacement definition?
how far the oscillation has moved in a given time
amplitude definition?
value of displacement from resting point to the crest
crest definition?
highest point
trough definition?
lowest point
wavelength speed = ?
speed = frequency x wave length
Example of longitudinal wave
Sound
Example of transverse wave
water ripples
what is compression?
when particles are close together
what is rarefaction?
particles are further apart.
what is a node?
where waves intersect/every half wavelength
what is an antinode?
maximum amplitude
what is a stationary wave?
energy is stored rather than transfered
frequency trend in electromagnetic spectrum?
frequency increases left to right.
