Crash Course Physics Waves

Definition: Crest

• The highest point of a transverse wave

• The lowest point of a transverse wave

• The center of a transverse wave

• The distance between two points on a wave

Definition: Trough

• The center of a wave

• The resting position of a wave

• The lowest point of a transverse wave

• The highest point of a transverse wave

What is the frequency of a wave?

• # of oscillations produced in a certain amount of time

• The distance the wave oscillates from it's resting position

• The lowest point of a transverse wave

• Resting point of a wave - no wave movement

What is the amplitude of a wave?

• Where there is no wave movement

• The distance the wave oscillates from it's resting position

• A disturbance that transfers energy from one place to another

• The distance between two corresponding parts of a wave
