  1. Mirrors Sec 19.1

  2. Law of Reflection • Review of Law: the angle of reflection is equal to the angle of incidence • We use ray diagrams to show how light rays change direction when they strike mirrors and pass through lenses.

  3. Plane Mirrors • Plane mirror –mirror with a flat surface • Plane mirrors create an image through these steps: • Light rays strike you and reflect • Reflected rays then strike the mirror

  4. Plane Mirrors • Plane mirror –mirror with a flat surface • Plane mirrors create an image through these steps: • The rays are reflected again to your eye • Your brain interprets the rays to come from behind the mirror.

  5. Plane Mirrors • Plane mirrors produce a virtual image (a copy of an object formed a point from which light appears to be coming)

  6. Concave Mirrors • A concave mirror has the reflecting surface curved inwards. • The curve causes the reflected rays to come together in a point called the focal point.

  7. Concave Mirrors • Concave mirrors can form either real or virtual images, depending on where the object is located. • Use in automobile headlights and flashlights

  8. Convex Mirror • A convex mirror has the reflective surface curved outwards. • Convex mirrors always cause light rays to spread out and form only virtual images. • Used for car side mirrors and store aisle mirrors.

  9. Concave Mirrors • Concave mirrors can form either real or virtual images, depending on where the object is located. • Use in automobile headlights and flashlights
