Words for E.S.

Words for electromagnetic spectrum quiz tomorrowww:D

infrared radiation A form of energy with wavelengths that are longer than red light; not visible but can be felt as heat; examples include the Sun and remote control devices.
visible light A mixture of all of the colors that you see in a rainbow; the different colors are because of the different wavelengths of visible light; red = longest wavelength, violet = shortest wavelength.
ultraviolet radiation A form of energy with wavelengths that are shorter than violet light; invisible; UV radiation can cause skin and eye damage.
radio waves A form of energy with the longest wavelength; cellular phones, GPSs, radios, TV, satellite radios, police scanners, and stars emit and/or make use of radio waves.
microwave radiation A form of energy with wavelength size between radio waves and infrared radiation; examples include microwave oven, Doppler radar, PAVE PAWS (detect incoming missiles or foreign flying objects)
x-ray radiation A form of energy with wavelength size between UV radiation and gamma radiation; this form of energy is used to take images of bones and other internal organs; stars emit x-ray radiation.
gamma radiation A form of energy with the shortest wavelength sizes - very powerful, used to treat cancer by killing/shrinking the cancer cells.
heat transfer Movement of heat energy between substances that are at different temperatures; heat energy is always transferred from the warmer substance to the cooler substance.
conduction Transfer of heat by direct contact with particles of matter; how particles of a solid become heated.
convection Transfer of heat by the movements of a heated fluid (liquid) or a heated gas.
density The amount of mass in a given space; mass per unit of volume (g/mL); less dense fluids or gases rise when heated because particles spread out and become less compact.
convection current The movement of a fluid or gas caused by differences in temperature; transfers heat from one part of the fluid or gas to another.
electromagnetic spectrum Full range of electromagnetic waves that travel from the sun and other stars through space.
radiation Transfer of energy in electromagnetic waves; occurs through empty space.
