1. Doppler Effect & Electromagnetism

2. How is sound a Wave? Discuss with a partner.
So if the energy of the sound wave dissipates over distances, what do you think happens to it as something moves away from you?

3. Doppler Effect
The apparent change in frequency of a sound wave caused by the motion of the wave and the observer.
Get closer to the source = more waves you observe
Farther away = less waves

4. Electromagnetic spectrum
A classification by wavelength into radio, micro,terahertz and visible light.
The behavior of Electro- magnetism depends on wavelength

5. ElectroMagnetism
The interaction of electric currents or fields and magnetic fields
Electromagnetic waves carry electromagnetic radiate energy through a space.

6. So how does electromagnetism work?
Energy is the ability to do work
You manipulate the electrical energy in objects
You put energy into that manipulation
Things have ability to move to your control
Objects move so long as they are in your area of effect, concentration, and give them the ability to do work (energy)
