Unit 6 Review - Waves, Sound, Light

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

How are Electromagnetic waves different from Mechanical waves?

• EM waves have very short wavelengths

• EM waves transmit energy instead of matter

• EM waves can travel through the vacuum of space (without particles)

• EM waves can change direction by reflection
