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.
