Reflection of Light Definitions Luminous objects generate their own light (the sun) Illuminated objects reflect light (the moon) Line of Sight a line from an object or image to your eyes (light from the
object travels along this line to your Slide 2 eyes) Line of Sight Both luminous & illuminated objects emit/reflect light in many directions.
Your eye sees only the very small diverging cone of rays that is coming toward it. Slide 3 Rays of Light
Incident Ray leaves the object and strikes the mirror Reflected Ray leaves mirror and strikes your eye The reflected ray is on the line of sight from the image to your eye.
Slide 4 Law of Reflection Angle of incidence equals angle of reflection. Slide 5 Law of Reflection
Normal line perpendicular to the mirror surface Angle of incidence angle between incident ray and normal
Slide 6 Angle of reflection angle between reflected ray and normal Law of Reflection Animation

Slide 9 Wet Road Glare Driving at night on a wet roadway results in an annoying glare from oncoming headlights. Slide 10
Observing an Image An image is a position in space from which all reflected light appears to diverge. Image formed by a plane mirror is called a virtual image.
Virtual images are formed in regions where there is actually no light Slide 11 Image Location Slide 12
Image Formed By Plane Mirror Image is virtual. Image is located as far behind the mirror as the object is in front of the mirror. Slide 13
