Conservation of Energy- Energy can not be created nor destroyed, but transformed from one

Conservation of Energy- Energy can not be created nor destroyed, but transformed from one type to another Closed system- Energy can not escape or enter Page 1

§ Source- Where it comes from § Sink- Where it flows (goes) § ENERGY

§ Source- Where it comes from § Sink- Where it flows (goes) § ENERGY ALWAYS FLOWS FROM HIGH LOW or SOURCE TO SINK Ex: Sun to Earth Page 1

Page 2 Energy Transfer from Sun Electromagnetic energy is a type of energy that

Page 2 Energy Transfer from Sun Electromagnetic energy is a type of energy that is radiated by the sun in the form of transverse waves

Electromagnetic Energy Page 2 • ALL OBJECTS THAT HAVE A TEMPERATURE GREATER THAN ABSOLUTE

Electromagnetic Energy Page 2 • ALL OBJECTS THAT HAVE A TEMPERATURE GREATER THAN ABSOLUTE ZERO EMIT (GIVE OFF) ELECTROMAGNETIC ENERGY • ***Higher temperature more radiated energy*** amplitude ***Put this key concept at bottom of page 2***

Electromagnetic Energy Page 2 • Transverse Wave- a wave that vibrates at right angles

Electromagnetic Energy Page 2 • Transverse Wave- a wave that vibrates at right angles to the direction at which it is traveling

Page 2 Parts of a Transverse Wave • Crest- top of a wave •

Page 2 Parts of a Transverse Wave • Crest- top of a wave • Trough- bottom of a wave • Amplitude- height of a wave

Parts of a Transverse Wave Page 2 • Wavelength-is the distance between two successive

Parts of a Transverse Wave Page 2 • Wavelength-is the distance between two successive crests or troughs

Frequency- is the number of waves which pass a certain point in a second

Frequency- is the number of waves which pass a certain point in a second The longer the wavelength, the lower the frequency The shorter the wavelength , the higher the frequency Page 2

The Electromagnetic Spectrum (EME) is a model of the different forms of Page 2

The Electromagnetic Spectrum (EME) is a model of the different forms of Page 2 radiation

All types of EME are similar: • they travel to you in transverse waves

All types of EME are similar: • they travel to you in transverse waves • they travel at the speed of light • are radiated Page 2
