14 Cards in this Set

  • Front
  • Back
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 <-->
