1. Reflection

2. Flat (plane) mirror

3. Virtual: image is formed behind mirror
di = do Image is same distance from mirror
hi = ho Image is same height as object

4. Spherical Mirrors Ray Tracing 1. Parallel : Focal Pt.
Focal Pt : Parallel
3. Center of curvature : Center of curvature

5. Example: What is the final intensity if a third polarizer is added in the middle oriented at 45o?

6. Sunglasses

8. The mirror Equation 1/f = 1/do + 1/di M = hi/ho = -di/do
di + : Real image
di - : Virtual image
M + : Upright image
M - : Inverted image
|M| > 1 : larger image
|M| < 1 : smaller image

9. An object is 3cm high and located 20cm from a concave mirror with a focal length of 5cm. Where is the image located? Is it real or virtual, upright or inverted, larger or smaller?
