Presentation on theme: "waves Mechanical If a medium is needed for the transfer of energy"— Presentation transcript:

1 waves Mechanical If a medium is needed for the transfer of energy
Electromagnetic If no medium is required

2 What is essentially needed to produce a wave:
Disturbance

3 For how long the wave runs?
Until runs out of energy

4 How particles of water moves?
Which wave wold have more energy a high wave or a short wave? The height of a wave is called AMPLITUD “is the maximum displacement from its equilibrium position”

5 Sound generator
