 * Energy-The strength and vitality required for mental activity.


 * Radiation-The emission of energy as electromagnetic waves.


 * Wavelengths-Distance between successive crests those are of a wave.


 * Frequency-The rate at which something occurs.


 * Reflect-(Of a surface or a body) throw back (heat, light, and sound) without absorbing it.


 * Refract-To measure the focusing characteristics like of someone's eyes.


 * Absorb-To engross the attention of someone.


 * 1) The electromagnetic spectrum is made up of only visible light.
 * 2) Microwaves are used to communicate with satellites because they can pass through parts of our atmosphere
 * 3) Mechanical waves such as sound cannot travel through space
 * 4) Waves in the electromagnetic spectrum with long wavelengths have the most energy
 * 5) Because we knowing how fast light travels and how it is reflected, we can use this information to figure out how far away objects are.
 * 6) Different types (wavelengths) of light are refracted (bent) differently.
 * 7) EXTRA CREDIT Using question 6: Why do you think this would be a problem when making a telescope using lenses?
 * 8) 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.
 * 9) Ultraviolet light from space is easily researched using ground telescopes.
 * 10) A star that emits mostly yellow visible light is hotter than a red star.
 * 11) Absorption lines in the visible spectra and patterns of reluctance can be used to tell us what distant objects like stars and planets are made of.

1. False, I said false because it's not just made up of visible light and there are radio waves, microwaves, Infrared, Visible light, Ultra Light, X-Rays, and Gamma. 2. False, The answer I said was false because microwaves have wavelengths and they are used in remote sensing and they used radar too. 3. True, I said true because these waves can be longer than a football field and they also carry signals for television and cell phones. 4. True, The answer I said was true because they broadcast the television station and they displayed on the television screen. 5. False, I said false because light travels in the colors of the rainbow and it has a short wavelength. 6. True, I said true because the bending depends on the speed and angle of light. 7. I think this would be a problem because you would see different things just because it is in a different position. 8. False, because special cameras and film can't detect changes in temperature. 9. False, I said false because telescopes are put on satellites to measures ultraviolet light not on the ground. 10. True, stars the have the most ultraviolet light are the hottest. Yellow stars have higher UV then red stars. 11. False, I said false because light bulbs can burn and they are broken into parts.
