______ are the tops of a transverse wave. Crests
______ are the very bottoms of a transverse wave. Troughs
______ the starting point of the wave. Restingpoint
In a ________, the particles move perpendicularly compared to the wave. Transverse Wave
A ________ has the particles move back and forth, just like the wave. Longitudinal Wave
_______ are the part of a longitudinal wave that are closer together. Compressions
_______ are where the particles are more spread out in a longitudinal wave. Rarefactions
______ is an activity involving a force and movement in the direction of the force. Work
_____ is the rate of doing work or the rate of using energy. Power
_____ is the number of waves that pass through a point at any time. Frequency
