2. What do you know about Mirrors? 1.We see objects because _____. a. light is reflected off of objects b. objects generate their own light c. both A and B 2. Possible shape(s) of mirrors are ___. a. Flat b. Concave c. Convex d. All of the above

3. 3. Convex mirrors cause light to ____. a. reflect up only b. diverge (spread) apart c. reflect down only 4. Concave mirrors cause light to ___. a. diverge (spread) apart b. reflect straight c. converge to a focal point

4. 5.Which two rules are NOT true about reflection? a. light travels in a straight line b. reflection is in an unpredictable pattern c. Angles of incidence and reflection are determined by the curve of the mirror

5. What do you know about lenses? 6.Refraction of light is _____. a. Change in direction b. change in speed c. Both A and B 7. Light travels faster in ____. a. air b. water c. no difference 8. Eye glasses work because they _____. a. change the speed of light b. change direction of light c. Both A and B

6. 9.Telescopes are _____. a. magnification of light b. both magnification and reflection of light c. reflecting with mirrors 10. Prisms break light into ____. a. dominant and recessive colors b. seven colors of the rainbow c. light colors vs. dark colors

7. Light Fact 1: Light always travels in straight lines

8. Light is energy that travels in waves of different wavelengths. Light Fact 2:

9. Light Fact 3: The different wavelengths create the energy we know as X-rays, Ultraviolet, Visible, Infrared, Microwaves and Radio waves.

10. Light Fact 4: The reflection of light from surfaces allows us to see objects that do not emit their own light.

11. Light Fact 5: When charged particles from the sun are captured by the Earth’s magnetic field it creates an effect we call the AURORA BOREALIS or Northern Lights

12. Light Fact 6: Convex mirrors cause waves to diverge Note that these behave as if there is a focus behind the mirror, called a virtual image

13. Light Fact 7: Only a convex lens can form a real image. Real images are inverted and smaller than the actual image
