| Question | Answer |
|---|---|
| What term describes the ability to do work? | Energy! |
| Name Earth's external heat engine. | The Sun. |
| How might you describe, "absolute zero"? | Coldest temperature, 0 degrees Kelvin, no energy at all! |
| Can you define electromagnetic energy? | Energy in wave form radiated by all objects whose temperature is above absolute zero. |
| How can we differentiate between different types of Electromagnetic Energy? | Wavelength. |
| All waves in the Electromagnetic Spectrum travel at what velocity? | Speed of Light. *( 186,000 miles per second ) |
| Which page in the ESRT would you turn to for the Electromagnetic Spectrum Table? | Page 14, bottom. |
| Does short wave length indicate high energy or low energy? (Gamma Rays) | High Energy. Shorter wave lengths than visible light will harm humans! |
| Does long wave length suggest high or low energy? (radio waves) | Low Energy, will not harm humans. |
| In the visible light part of the electromagnetic spectrum, is blue color high or low energy, short or long wave length? | High energy, shortest wave length! |
| What term indicates the bending of light? | Refraction. |
| What do we call light that bounces off of material? | Reflection. |
| Name the term that suggests energy is "taken into"? | Absorbed. |
| Why is a freshly fallen snow field such a poor absorber of energy? | Color white, texture smooth. |
| Why is the jungle such a good absorber of energy? | Color dark, texture rough. |
| How can we complete the phrase," A good absorber is a good ________". | Radiator. "Easy in, Easy out!" Heats easily, Cools quickly. |
| Which color has the longest wave length that the human eye can detect? | Red. And long wave length suggests low energy! |
| Name the pages in the Regents Review Book that are reviewed in this exercise! | Pages 82 through 84 in the Prentice Hall Regents Review Book. |
