Waves move energy not matter.
Transverse waves move parallel to the direction of their wave motion.

From this picture, the amplitude is:
What is the distance from one compression to the next in a longitudinal wave?
If the frequency of a wave increases, what decreases?
On a longitudinal wave, in which areas are particles farthest apart?
What is the lowest point of a wave called?
The measurement from crest to crest or from trough to trough is called what?
What is the unit for frequency?
If
then, what is
If the wavelength of a transverse wave is 0.5 m and the frequency is 1 Hz, what is the waves velocity? (Make sure to include the correct unit!)
If the velocity of a wave is 20 m/s and the frequency of the wave is 5 Hz, what is its wavelength?
Diffraction is ...
What type of reflection causes fiber optics to work?
The sky is blue because the molecules in the atmosphere are scattering the sun's rays causing shorter wavelengths.
