Define the follow ing terms

Energy - power that humans can use comes from heat, electricity, etc.

Radiation - form of rays of energy that we cannot see with the naked eye.

Wavelength - energy traveling from one point to another.

Frequency - a number of something that happens during a particular period.

Reflect - when light or something bounces off a surface and comes back in the opposite direction.

Refract - to make light go in a new direction or at a new angle.

Absorb - to take in or to draw in from somewhere or something.

Information from class notes, The order is from lowest energy on the left to highest energy. Electromagnetic Spectrum Radio Microwave Infrared Visible UV X-Ray Gamma Ray

Answer each question as TRUE or FALSE. After each answer, write one or two sentences from the website that provides evidence to support your answer. []


 * 1) The electromagnetic spectrum is made up of only visible light. False, because cell phones use it and we can see the cell phone and its light.
 * 2) Microwaves are used to communicate with satellites because they can pass through parts of our atmosphere. True, it can penetrate clouds, haze, rain, etc which is helpful to communicate with Satalites.
 * 3) <span style="font-family: Arial,Helvetica,sans-serif;">Mechanical waves such as sound cannot travel through space. True, it can not only travel through solid materials and air, but also space vacuum.
 * 4) <span style="font-family: Arial,Helvetica,sans-serif;">Waves in the electromagnetic spectrum with long wavelengths have the most energy. False, energy increases as wavelengths get shorter
 * 5) <span style="font-family: Arial,Helvetica,sans-serif;">Because we knowing how fast light travels and how it is reflected, we can use this information to figvure out how far away objects are. false, The longer the response time, the farther away the surface and lower the elevation. A shorter response time means the surface is closer or higher in elevation.
 * 6) <span style="font-family: Arial,Helvetica,sans-serif;">Different types (wavelengths) of light are refracted (bent) differently.true, Different wavelengths of light are slowed at different rates, which causes them to bend at different angles.
 * 7) <span style="font-family: Arial,Helvetica,sans-serif;">EXTRA CREDIT Using question 6: Why do you think this would be a problem when making a telescope using lenses?
 * 8) <span style="font-family: Arial,Helvetica,sans-serif;">Even though we can’t see it with our eyes, cooler objects such as planets and people emit infrared waves that can be studied with special instruments. True, many objects in the universe are to faint to see, but can be detected by infrared.
 * 9) <span style="font-family: Arial,Helvetica,sans-serif;">Ultraviolet light from space is easily researched using ground telescopes.True, Many objects in the universe are too cool and faint to be detected in visible light but can be detected in the infrared.
 * 10) <span style="font-family: Arial,Helvetica,sans-serif;">A star that emits mostly yellow visible light is hotter than a red star.True, because if we heat something it turns to red, then yellowish white and if we heat it more it turns to bluish-white.
 * 11) <span style="font-family: Arial,Helvetica,sans-serif;">Absorption lines in the visible spectra and patterns of reflectance can be used to tell us what distant objects like stars and planets are made of. True, because
