3. Define wave: _________________________________________ Can you think of 3 examples of waves? _________________________________________ 1

4. Recall the Law of Conservation of energy: __________________________________________ How does the law of conservation of energy apply to a pebble making waves? (This is NOT in the reading! It is from the past! Apply what you know! I know you know if you think!!) __________________________________________ __________________________________________ 2

5. Have you ever noticed that approaching waves bump against your boat but do not carry it? You kind of bobble. Did you know that waves do not even carry water with them? They simply transfer energy to the water molecules next to them. Waves will travel only as long as they have energy.

6. Define medium: _____________________ __________________________________ Mediums can be _______________, _______________,_______________, or a _________________ of these. Not all waves need a medium. ____________ waves and ______________ waves can travel through space. Waves that travel only through matter are ______________waves. The two types of mechanical waves are ____________and ______________ waves. 3
