1. __(B.19): Describe how light is absorbed, refracted, and reflected by different surfaces.

2.  Concave*Lens  Converge  Convex  Diverge  Invert  Image  Beam  Ray

3.  Curved inward  If close to the mirror, then the image looks larger and right side up no matter where the observer stands  If far enough away from the mirror, then the image will look upside down  The reflected images will converge into one image

4.  Curved outward  When light hits a convex mirror, it is reflected by the mirror at the same angle which it strikes the mirror  The curve of the surface causes light rays farther from the center of the mirror to diverge or be reflected  The reflected images look farther away

5.  The curve of a concave mirror causes light rays to converge  To cause light rays to come together in one place

6. *Convex Mirrors make things look smaller, making things diverge *To go or extend in different directions

7.  To turn upside down; to reverse the order

8.  The picture of an object produced by a lens or mirror.  The reproduction of an object formed by a mirror or lens.

9.  A specially shaped piece of refractive material designed to change the way objects on one side of it look by changing the paths of light rays that pass through the material.

10.  Light waves are reflected off a mirror at the same angle at which they strike the mirror.  Example: Reflection and Mirrors Lab- remember that each light beam reflected off of the mirror at the same angle they entered the mirror

11.  A reflection will be lined up face-to-face wit the object that produced it, and appear as far behind the reflective surface of the mirror as the object is in front of it.

12.  A narrow beam of light that travels in a straight line from a light source

13.  To bounce off a surface

14.  Causes light rays to diverge and make objects look smaller

15.  Causes light rays to converge and make images that are up close seem large  Images that are farther away appear upside down

16.  Nearsighted individuals can see things close up but can’t see things far away  Farsighted individuals can see things far away but can’t see things close up  20/20 vision is considered to be normal vision (no correction needed)

17.  The bending of light as it passes from one material to the next  Ie. Light beam through water
