Energy- power that is gotten from physical or chemical resources, also to provide light or heat to hard to work projects.

Radiation- e emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.

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

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 it is also made up of Radio Microwave Infrared Visible UV X-Ray Gamma Ray
 * 2) Microwaves are used to communicate with satellites because they can pass through parts of our atmosphere. True because it can pass through storms, and stuff to help look where storms are.
 * 3) Mechanical waves such as sound cannot travel through space. True because there is no molecules to pick up the sounds in space.
 * 4) Waves in the electromagnetic spectrum with long wavelengths have the most energy.True because since Radio waves have the longest wave they are the biggest and since gamma rays has the smallest wave the are the shortest.
 * 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 because the shorter the response time the closer the object is and longer the response time the further something is.
 * 6) Different types (wavelengths) of light are refracted (bent) differently.True different wavelengths of light are slowed at different rates, which cause them to bend at different angels.
 * 7) 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 at different colors the imaged would be distorted.
 * 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 because things that can't be seen by visible light can be seen by in fared such as people and planets.
 * 9) Ultraviolet light from space is easily researched using ground telescopes. False scientist use data from satellites because earths atmosphere absorbs so much high uv radiation
 * 10) A star that emits mostly yellow visible light is hotter than a red star. True because the color yellow has more energy than red
 * 11) 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 the universe.
