Raging martians invaded Roy G. Biv using x-ray guns.
Electro magnetic Spectrum- all of the frequencies or wavelengths of electromagnetic radiation.
Summary of the Section 2 of the reading:
- All electromagnetic waves travel at the speed of light, which is 300,000 km/s. Electromagnetic waves only differ by wavelength and frequency.
- The entire range of EM waves is called the electro magnetic spectrum.
- Radio waves are used for communication.
- Microwaves are used in cooking and radar.
- The absorption of infrared waves is felt as increase in temperature.
- Visible light is a narrow range of wavelengths that humans can see. Different wavelengths are seen as different colors.
- Ultraviolet light is used for killing bacteria and for producing vitamin D. in the body. Overexposure to ultraviolet light can cause health problems.
- X-Rays and gamma rays are electromagnetic waves that are often used in medicine. Over exposure to these kinds of waves can damage or kill living cells.
