Needs a medium to pass through

Longitudinal waves

Like a snake- moves it's body one way and travels in another.
Vibrates up and down, but travels forward.
Light waves

Transverse waves

Remember: Both these waves have amplitude
More amplitude = more energy

Hotspot

Which of these areas shows the direction of vibration in a transverse wave?
