2A Electromagnetic Spectrum What s the Wavelength? Foldable guided instructions key 100
Directions: Create your Electromagnetic (EM) Spectrum Foldable 1. Cut along the dashed lines up to the solid mid-line. 2. Fold hotdog style along the solid mid-line. 3. Write the missing wavelength labels on the flaps. 4. Research the EM Spectrum to find out each EM wavelengths : wavelength size comparisons and identify longest and shortest EM waves wavelength frequency (highest and lowest only) example of the wavelength (source, use, etc.) 5. Use the clues from EM Spectrum printed on the foldable to assist you. 101

Wavelength: Create your Electromagnetic (EM) Spectrum Foldable 1. Define: Directions: Ultraviolet Rays Infrared Rays Gamma Rays Radio Waves Visible Light Microwaves X-Rays (top edge)
Radio Waves Longest electromagnetic (EM) wavelengths Lowest EM frequencies Not harmful to living organisms 106
Microwaves A type of radio wave Not dangerous to living organisms Speed guns, and of course microwave ovens, use microwave EM waves 107
Infrared Rays IR wavelengths are shorter than radio waves and microwaves IR waves can be felt as heat Heat lamps and infrared cameras use IR electromagnetic waves 108
Visible Light Wavelengths that are longer than UV, X-ray, and Gamma Ray waves Humans can see this form of electromagnetic radiation White light can be separated into red, orange, yellow, green, blue, indigo, violet 109
Ultraviolet Rays UV electromagnetic radiation can damage or kill living cells UV waves cause sunburns and skin cancer in humans Used as a disinfectant 110
X-Rays X-rays penetrate most matter Dangerous to living organisms Too much exposure to X-rays can cause cancer in humans 111
Gamma Rays Shortest electromagnetic (EM) wavelengths Highest EM frequencies Most penetrating and dangerous of all electromagnetic waves to living things, including humans 112
