| Which color has the longest wavelength? | Red |
| A bundle or burst of light energy is called a: | photon |
| A band of color with dark lines running through it produces a(n): | absorption spectrum |
| What does a prism do? | Separates visible light into colors |
| An unbroken band or block of color produces a(n): | continuous spectrum |
| What term refers to a change in wavelength, brightness, or sound that occurs when an object moves toward or away from a source? | Doppler effect |
| A reflecting telescope produces an image using a(n): | mirro |
| The source of the sun's energy is: | nuclear fusion |
| Using the Doppler effect, astronomers can determine a star's: | movement toward or away from Earth |
| A refracting telescope produces an image using a(n): | (objective) lens |
| Sunspots appear dark because they are: | relatively cool |
| Which famous scientist first used a telescope for astronomical observations? | Galileo |
| Which property of an optical telescope is associated with sharper, clearer images? | resolving power |
| The layer of the sun that readiates most of the light that reaches Earth is the: | photosphere |
| The outermost layer of the sun's atmosphere is called the: | corona |
| Which part of the sun lies directly above the visible "surface" of the sun? | chromosphere |
| What effect do solar flares have on Earth? | auroras |
| The thin red rim seen around the sun during a total solar eclipse is called the: | chromosphere |
| The sun's surface is made up mostly of: | hydrogen |
| Streams of electrons and protons that shoot out from the sun's corona make up the solar: | winds |
| Scientifically speaking, spproximtately how long has the sun been burning? | 5 billion years |
| What are clouds of glowing gases that arch high above the sun's surface called? | prominences |
| What two elements are involved in the production of energy on the sun? | hydrogen and helium |
| In what part of the sun does nuclear fusion occur? | the core |
| List the colors of the visible spectrum in order from shortest to longest? | Violet, Indigo, Green, Yellow, Orange, Red |
