2. Electromagnetic Spectrum Jigsaw
Your group is going to become an expert in an area of the electromagnetic spectrum. Some of the things to include in your poster:
What are the characteristics of this type of radiation (wavelength, frequency, key facts)?
Where is this type of radiation located on the electromagnetic spectrum in relation to other kinds of radiation?
How is it used or found in our everyday lives or in certain industries? Identify and explain at least two uses.
Use textbook and NASA packet to find info

4. Electromagnetic Energy
Electromagnetic Waves (radiation): Are transverse waves produced by the motion of electrically charged particles. Electromagnetic Spectrum: Total Range of all electromagnetic waves.

5. Electromagnetic Spectrum

6. Electromagnetic Spectrum
Gamma Rays – strongest waves
X-Rays – used to view bones and teeth.
Ultraviolet (UV) – tanning and sunburn.
Visible Light – allows us to see color

7. Infrared – radar systems, remote controls
Microwave – used for aircraft navigation.
Radio waves
FM – high frequency radio and TV.
AM – low frequency radio.
Long Radio waves – used by astronauts to communicate to Earth from the moon

8. Electromagnetic Energy
Usually the shorter the wavelength the more dangerous the electromagnetic wave (higher frequency). Which portion of the spectrum is most dangerous?
Gamma Rays.

9. Visible Spectrum Definition:
The ONLY portion of the spectrum that can be seen by the naked eye.
ROY G BIV gives us the order from the longest wavelength - (RED) to the shortest wavelength - (VIOLET).
White light (sunlight) is a mixture of ALL visible light.
