3. Radio waves have the longest wavelength which is longer than 30 centimeters All radios and televisions use radio waves. Radio waves are also used in walkie talkies Walkie talkies Satellite dish

4. Microwaves have a wavelength between 1 millimeter and 30 centimeters. Microwaves (obviously) are used for microwave ovens. (gasp!) Microwaves are also used in cell phones because they can send messages over long distances. Cell phones microwave

5. Infrared waves have a wavelength between 700 nanometers and 1 millimeter The sun produces infrared which you feel as heat. Infrared also helps your night vision. Night vision sun

6. Visible light's wavelength ranges from 400 nanometers to 700 nanometers Visible light helps us to see colors. The sun produces a kind of visible light called white light. ROY G. BIV Sun beam

7. X-rays have a wavelength ranging between.001 nanometers and 600 nanometers X-rays are used to take pictures of your bones because they can go through skin and muscles but not bones. X-rays are also used in public security cameras Security camera bones

8. Ultraviolet rays have a wavelength between 60 nanometers and 400 nanometers Too much ultraviolet rays can cause sunburn They make lamps that use ultraviolet rays that kill bacteria. sunburn lamp

9. Gamma Rays Gamma rays have a wavelength of less than.1 nanometers Gamma rays are used to treat some forms of cancer Gamma Rays are also used to kill harmful bacteria in foods Cancer cell hamburger
