P6: LONGITUDINAL AND TRANSVERSE WAVES Flashcards
What is a transverse wave?
a wave that vibrates perpendicular to the direction of energy transfer
What is an example of a transverse wave?
light waves
What is a longitudinal wave?
a wave that vibrates parallel to the direction of energy transfer
What is an example of a longitudinal wave?
sound waves
How fast does sound travel?
330 m/s
How fast does light travel?
3x10^8 m/s
What is frequency?
the number of waves passing a point per second
What is the equation that links time period and frequency?
time period (s) = 1 / frequency (Hz) (T = 1/f)
What is wavelength?
-the distance between 1 peak/trough and the next peak/trough (transverse)
or
-the distance between compressions (longitudinal)
What is amplitude?
the distance between the peak/trough and equilibrium
