amplitude
|
distance between lowest or highest point to the equilibrium
|
|
crest
|
highest point in a wave
|
|
trough
|
lowest point in a wave
|
|
wavelength
|
LAMBDA
distance between 2 adjacent crests/troughs [units of lenght] |
|
period
|
T
time it takes to complete once wave, oscillation, vibration, or cycle [seconds] |
|
frequency
|
f or v
numer of complete waves passing in an amount of time [Hz] --> cycles/second f=1/T |
|
speed
|
v
waves move a distance (lambda) in a time (T) lambda=vT speed of sound= 340 m/s speed of sight= 300,000km/s |
|
spectrum
|
range of frequencies (or wavelengths) of a particular type of wave.
|
|
wave
|
a rhythmic (has a pattern) disturbance that carries energy through a medium (vacuum, matter, or air)
|
|
sound waves in air
|
v= 343m/s
|
|
water waves
|
no set speed
|
|
electromagnetic radio waves
|
v= 3x10^8m/s
|
|
transverse waves
|
energy is given -up and down- but waves travels <-->
the direction of the waves is perpandicular to the direction of the energy input |
|
longitudinal waves
|
energy is given <--> and the wave travels <-->
