Define the following terms


 * Energy**- the ability of producing power to make things able to work


 * Radiation**-a type of energy, that has different types, a way of energy transfer, and can be harmful


 * Wavelength**- energy that is being transferred from one thing to another


 * Frequency-** condition of happening often


 * Reflect-** a shadow, or light beam that hits something and bounces back, reflects back perfectly


 * Refract**- doesnt get reflected perfectly, gets changed


 * Absorb**- soak up, take in

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, this is false because it contains UV, gamma, microwaves, radios.
 * 2) Microwaves are used to communicate with satellites because they can pass through parts of our atmosphere- TRUE, this Is true because microwaves transmit information from one place to another. Microwave energy can penetrate haze, light rain and snow, clouds, and smoke.
 * 3) Mechanical waves such as sound cannot travel through space- TRUE, this is true because for it to work you have to have some kind of medium.
 * 4) Waves in the electromagnetic spectrum with long wavelengths have the most energy- FALSE, this is false because it has the lowest 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. TRUE, this is true because we can measure it using light years.
 * 6) Different types (wavelengths) of light are refracted (bent) differently. - TRUE, this is true because it bends at different angles.
 * 7) EXTRA CREDIT Using question 6: Why do you think this would be a problem when making a telescope using lenses? This would be a problem because the light bends the figure, and the figure would not be clear.
 * 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. TRUE, this is true because we emit radiation as humans.
 * 9) Ultraviolet light from space is easily researched using ground telescopes. FALSE, this is false because the atmosphere absorbs UV radiation.
 * 10) A star that emits mostly yellow visible light is hotter than a red star. TRUE, this is true because a red star is cooler than all the other stars.
 * 11) Absorption lines in the visible spectra and patterns of refletance can be used to tell us what distant objects like stars and planets are made of. TRUE, this is true because each element has lines, and each has a specific pattern.
 * 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?

1. What is the Problem? The best ranked telescope.
 * Readiness Questions**

2. Who is the client? Luke S. Walker

3. What is the client asking your team to do? The client is asking my team to rank the telescopes.

4. What things do you need to include in your solution?

data for each telescope how each one works best range of view what one has the best resolution best quality best time of focus best spectrograph best field of view

5. Do you think there is more than one correct answer to what the client is asking? Why or why not? yes, I do think that there is more than one correct answer to this, I think this because it all depends on what you think is the most important thing about a telescope, and what you are planning to look at with this telescope.
