1. Mirrors and Lenses Chapter 23, Section 1

2. Mirror and Lens Assignment Use p. 668 – 673 in your text Draw the following pictures ◦ Plane mirror ◦ Concave mirror ◦ Convex mirror ◦ Lens ◦ Concave lens ◦ Convex lens Define each State what type of image each will form Give an example where each may be used For each drawing show how light rays interact with the mirror or lens!

3. What is a ray? It is an arrow that we use to show the path of a light wave.

4. Plane Mirrors A mirror that has a flat surface (like your bathroom mirror!)  The image is right side up and the same size as the actual object. The only difference is that it appears backwards!  The image appears to be the same distance from the mirror, just on the other side!

5. Concave Mirrors  A mirror that is curved inward.  Can create a larger or smaller image  The image will appear upside down  Make-up mirror

6. Convex Mirror  A mirror that curves outward  It produces an image that is right side up and smaller than the original.  Useful because they can make images of large areas.

7. What is a Plane Lens? A lens is a transparent object that forms an image by refracting or bending light. Cameras, telescopes and movie projectors all use lenses to create images.

8. Convex Lens A lens that is thicker in the middle than at the edges. Used to MAGNIFY things Used in magnifying glasses, camera lenses and some eyeglasses. Used to correct farsightedness

9. Concave Lens A lens that is thinner in the middle than at the edges Causes light waves to bend away from each other Used in microscopes, eyeglasses and some telescopes Used to correct nearsightedness
