Question | Answer |
---|---|
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. |
