Optics: Reflection of Light in Mirrors

1. OPTICS (Mirrors) Prepared by: Ms. Jasmine Nikki M. Versoza

2. MIRROR A reflective surface that bounces off light, thus producing a real or virtual image

3. PLANE MIRROR A flat mirror that sends light out from itself in multiple directions. The image formed by a plane mirror will always be the same size as the original object.

4. 12 inches 12 inches

5. PLANE MIRROR It is virtual It is erect and of the same size as the object It is laterally inverted

6. EXERCISE For each of the following cases, draw a ray diagram to show how the light rays reach the observer, and to show the position of the virtual image in the mirror. Trace at least two light rays from each object.

7. EXERCISE 1. 2.

8. EXERCISE 3. 4.

9. CURVED or SPHERICAL MIRRORS Concave Mirror Convex Mirror

10. CONCAVE MIRROR It bends light further away in the middle, more like the inside of a bowl . How images appear depends on the proximity of objects to the mirror.

11. CONVEX MIRROR It curves light away from its middle, like the outside portion of a bowl . This type of mirror will produce only smaller and virtual images .

12. RAY DIAGRAMS Diagrams which are used to determine the location, orientation, size, and type of image formed in mirrors and lenses
