Waves
Central Concept: Waves carry energy from place to place without the transfer of matter.

4.2 Distinguish between mechanical and electromagnetic waves.
4.3 Distinguish between the two types of mechanical waves, transverse and longitudinal.
Slinkies
Loudspeakers
4.4 Describe qualitatively the basic principles of reflection and refraction of waves.
Refraction
Water glasses
Binoculars
Rear View Mirrors-Prismatic Glass
4.5 Recognize that mechanical waves generally move faster through a solid than through a liquid and faster through a liquid than through a gas.
4.6 Describe the apparent change in frequency of waves due to the motion of a source or a receiver (the Doppler effect).
