 * Wavelength- Space in between two wave crest.
 * Frequency-the rate at which vibration occurs that constitutes as a wave
 * Reflect- throw back or not to absorb
 * Refract- make a change of direction when it enters an angle
 * Absorb- to hold in

**Answer each question as TRUE or FALSE. After each answ **er, 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, visible light is only a part of the electromagnetic spectrum.
 * 1) Microwaves are used to communicate with satellites because they can pass through parts of our atmosphere
 * True, they are used to communicate with satellites because they can pass through parts of our atmosphere.
 * 1) Mechanical waves such as sound cannot travel through space
 * True, they cannot travel through space.
 * 1) Waves in the electromagnetic spectrum with long wavelengths have the most energy
 * False, the shorter the wavelength the more energy it has
 * 1) 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.
 * True: This reflective behavior of light is used by lasers the shorter response time the closer something is. The longer the further away it is.
 * 1) 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.
 * 1) EXTRA CREDIT Using question 6: Why do you think this would be a problem when making a telescope using lenses?
 * If they bend at different colors the image would be distorted.
 * 1) 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: Things that can't be seen by visible light can be seen by infared such as people and planets
 * 1) Ultraviolet light from space is easily researched using ground telescopes
 * False: Scientists use data from satellites because earths atmosphere absorbs so much high energy uv radiation.
 * 1) A star that emits mostly yellow visible light is hotter than a red star.
 * True, the color yellow has more energy than red, because it has more energy in it.
 * 1) 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: These patterns can provide important clues that reveal hidden properties of objects in our universe

** Reflection Questions ** 1. What characteristic does your group feel is most important in your ranking system? 2. Why do you feel this is more important than the others? 3. Can you properly explain your selection process?

Readiness Questions1. What is the Problem? 2. Who is the client? 3. What is the client asking your team to do? 4. What things do you need to include in your solution? 5. Do you think there is more than one correct answer to what the client is asking? Why or why not?
