1. REVIEW #1

2. WHAT IS ASTRONOMY?

3. IT IS THE SCIENCE THAT STUDIES OBJECTS IN SPACE (OFF PLANET EARTH).

4. MANNED AND UNMANNED SPACE PROBES CAN BE USED TO STUDY OBJECTS CLOSE TO EARTH, BUT WHAT IS THE MOST IMPORTANT TOOL THAT SCIENTISTS CAN USE TO STUDY DISTANT OBJECTS?

5. TELESCOPES (LIGHT)

6. WHAT ARE THREE ADVANTAGES THAT A TELESCOPE WOULD HAVE OVER USING THE HUMAN EYE?

7. 1)A TELESCOPE CAN GATHER MORE LIGHT. THIS WOULD HELP IN SEEING FAINT OBJECTS. 2)A TELESCOPE CAN MAGNIFY DISTANT OBJECTS. 3)TELESCOPES CAN USE LIGHT AT WAVELENGTHS OTHER THAN VISIBLE LIGHT.

8. WHAT IS LIGHT?

9. IT IS A FORM OF ENERGY THAT HAS BOTH WAVE AND PARTICLE PROPERTIES.

10. WHAT IS THE WAVELENGTH RANGE OF VISIBLE LIGHT?

11. 400 TO 700 nm

12. AS THE WAVELENGTH OF LIGHT INCREASES, THE ENERGY PER PHOTON ___________________.

13. AS THE WAVELENGTH OF LIGHT INCREASES, THE ENERGY PER PHOTON ___DECREASES_______.

14. NAME THREE THINGS THAT ASTRONOMERS CAN USE LIGHT TO MEASURE.

15. 1.SURFACE TEMPERATURE OF STARS 2.ELEMENTS PRESENT IN STARS AND NEBULAES 3.SPEED AT WHICH OBJECTS ARE MOVING 4.IF THERE ARE PLANETS AROUND A STAR 5.AGE OF STARS

16. HOW CAN ASTRONOMERS USE TELESCOPES TO COLLECT MORE LIGHT? 1.USE LARGER MIRRORS 2.MAKE TIME EXPOSURES
