Waves and Energy

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

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

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.

POTENTIAL ENERGYKINETIC ENERGY NuclearThermal ChemicalElectromagnetic Electric

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

Energy

Waves Transfer energy from one place to another

Types of waves Longitudinal waves Transverse waves

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

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

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

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

Parts of the Wave Amplitude- height of the wave

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