3 Waves Flashcards
Waves transfer energy …
without a transfer of matter
Transverse
Travsverse waves have vibrations that are …
parallel to the direction of the wave
Give 3 examples of:
Transverse waves
Light - EM Spectrum
Water
Secondary seismic waves
Longitudinal
Longitudinal waves have oscillations that are…
parallel to the direction of the wave
Give 2 examples of:
Longitudinal waves
Sound
Primary seismic waves
Define:
Amplitude
The maximum displacement of any particle/wave from its undisturbed position (equilibrium)
WAVES
difference between longitudinal and transverse waves
transverse = wave that vibrates perpendicular to the direction of the oscillation
e.g. light (EM Spectrum)
longitudinal = wave that vibrates parallel to the direction of the oscillation
e.g. sound
define wavefront
2 or more waves moving together have wavefronts, imaginary planes connect points on adjacent waves, vibrate together
define amplitude
maximum displacement of particles from their equilibrium position.
define wavelength
distance between a particular point on one cycle of the wave and the same point on the next cycle.
define frequency
number of waves passing a particular point per second. Is measured in Hertz (Hz).
define time period
time it takes for one complete wave to pass a particular point
waves transfer energy and information without transferring _______
matter
wavespeed =
wavelength x frequency
v = lamda x f
m/s = Hz x m
