1 Waves and Energy

2 What is Energy?? Is the ability to do work….. Now try it in your own words:??? An ability to cause change

3 What are the types of Energy? Potential Kinetic Chemical Thermal Electromagnetic Electric Nuclear

4 What are the two main types of Energy? Potential Kinetic All other energies fall under one of these two. Make a chart with your lab partner and place the types of energy under one of these.

5 POTENTIAL ENERGYKINETIC ENERGY NuclearThermal ChemicalElectromagnetic Electric

6 What is the law of conservation of Energy? Energy cannot be created or destroyed. However… energy can be transferred.

7 Energy

8 Waves Transfer energy from one place to another

9 Types of waves Longitudinal waves Transverse waves

10 Up and down Examples: -light - The Wave - See transverse waves

11 Longitudinal Waves Examples: – Sound - See longitudinal wavesSee longitudinal waves

12 Parts of a Wave Medium- what the wave passes through out

13 Parts of the Wave Wavelength- distance from crest to crest, or trough to trough

14 Parts of the Wave Amplitude- height of the wave

15 Describing a wave Frequency- the number of waves made in one second Frequency Measured in hertz (Hz)
