Chemistry Electromagnetic Radiation Video Clips Notes The Electromagnetic Spectrum: NASA. 1)Radiation travels at the speed of _____________________ in packets of energy and bibrates in _____________________. 2)The electromagnetic spectrum classifies the wide range of electromagnetic radiation using _____________________ and frequency. 3)the electromagnetic spectrum is divided into _____________________ categories for identification. 4)The categories of electromagnetic radiation include the following: a. _____________________ b. radiowaves c. infrared d. _____________________ e. ultraviolet f. x-rays g. _____________________ 5) A. Radiowaves have _____________________ wavelengths and are _____________________ energetic. B. They are used for _____________________ in the form of radio and TV broadcasts. 6)Microwaves have _____________________ wavelengths and are used for _____________________, communications, and radar. 7)Infrared radiation can’t be seen, but they can be _____________________ You can feel infrared as _____________________. 8)In the visible spectru, the color depends on its _____________________. Red has a long _____________________ and less energy, and violet light waves are much _____________________ and are the most energetic of all visible light. 9)Ultraviolet rays are the ones that tan or _____________________ your skin. The sun is hot enough to emit some ultraviolet light. U.V. tells astronomers about hot _____________________ stars and hot _____________________ stars. 10)X-rays are move _____________________ than ultraviolet rays. When x-rays are used to take pictures of our bodies the bones _____________________ the x-rays while the soft tissure does not. ElMagRadVideoclipsLCSD2

11) _____________________ have the highest energy and the shortest wave lengths of all. Certain radioactive materials emit _____________________. They may be used in some _____________________ treatments, but too much can cause severe illness.

The Electromagnetic Spectrum: Frontline. 1)Microwaves, visible light, and radio waves are all fundamental forms of _____________________. 2)Electromagnetic radiation is carried as particles called _____________________ that radiate in waves. 3)All photons travel at the speed of _____________________ 4)Photons vibrate at different _____________________ depending on the nergy othey’re carrying. 5)the many types of energy are called the electromagnetic _____________________ 6) _____________________ rays, like from a nuclear explosion, are high energy. The vibrate at high frequencies: 10 ____ Hertz (Hz). 7) _____________________ vibrate at a lower frequency. 8)U.V. waves are the third most energetic. The can give you a ____________________. 9) _____________________ is the part of the electromagnetic spectrum we can see. Photon energies of the radiation are great enough to excite electrons and molecules. 10)Lower frequencies don’t have enough energy to do that. Microwaves only have enough energy to _____________________. 11)Lower frequencies are used for _____________________ phones, _____________________, _____________________ radio, and finally _____________________ radio. 12)Everyday we are bombarded with electromagnetic _____________________ from many parts of the spectrum.
