1. Notebook # 8 Bellringer: 1.Mirrors are used in many different ways. Name five different technological applications for mirrors. 2.Which color shirt, black or white, would feel the coolest on a hot, sunny day? Why?

2. I. Reflection of Light A.Light Ray –a line in space that matches the direction of the flow of radiant energy. Blue = incoming light Red = reflected light

3. B. Rough surfaces –Results in diffuse reflection – an unclear image. Blue = incoming light Red = reflected light

4. C. Smooth surfaces –Smooth surfaces produce a sharp image by reflecting parallel light waves in only one direction. Blue = incoming light Red = reflected light

5. Angle of incidence (i) Angle of reflection (r) i = r 1.The law of reflection – Angle of incidence (i) is equal to the angle of reflection (r).

6. II. Mirrors A. Virtual Image –Image formed in a plane mirror. 1.Image appears to come from behind the mirror.

7. B. Real Image –An inverted image in front of the mirror. 1.Real images can be formed by a concave mirror.

8. III. Seeing Color A.Additive Primary Colors –Red, Green, Blue B. Subtractive Primary Colors –Yellow, Magenta, Cyan 1.Adding all three together produces white light. 1.Adding all three together produces black.
