  1. LIGHT AND OPTICS Light and Color Reflection and Refraction
  2. 1. 2. 3. 4. CHAPTER 17 OBJECTIVES Describe the functions of convex and concave lenses, a prism, and a flat mirror. Describe how light rays form an image. Calculate the angles of reflection and refraction for a single light ray. Draw the ray diagram for a lens and a mirror showing the object and image. fiber-optic-circuit-acts-likea pipe-forlight. 6. Describe the difference between a real image and a virtual image and give an example of each.
  3. 17.1 REFLECTION AND REFRACTION Key Question: How do we describe the reflection and refraction of light?
  4. REFLECTION AND REFRACTION The overall study of how light behaves is called optics The branch of optics that focuses on the creation of images is called geometric optics, because it is based on relationships between angles and lines that describe light rays. Object Light rays
  5. REFLECTION AND REFRACTION A lens is an optical device that is used to bend light in a specific way. A converging lens bends light so that the light rays come together to a point. A diverging lens bends light so it spreads light apart instead of coming together. Light rays Sun Hot spot 4 Magnifying glass
  6. REFLECTION AND REFRACTION Mirrors reflect light and allow us to see ourselves. A prism is another optical device that can cause light to change directions. A prism is a solid piece of glass with flat polished surfaces. Basic optical devices p rism Mirror Converging lens 11 Diverging lens
  7. LAW OF REFLECTION 'Ray d iegrarn normal line 300 1 Law of reflection incident ray reflected ray M irror light-ray-is incident ona plane mirror-with a80 degree angle—--- of incidence. Sketch the incident and reflected rays and determine the angle of reflection.
  8. REFRACTION When a ray of light crosses from one material to another, the amount it bends depends on the difference in index of refraction between the two materials. Refraction from air into diamond Air Diamond n = 242 Refraction from air into water Air 28 Water 1.33 130
  9. LAW OF REFRACTION Snell's law is the relationship between the angles of incidence and refraction and the index of refraction of both materials. Angle of incidence (degrees) ni sin = n Angle of refraction (degrees) sin
  10. CALCULATE THE ANGLE OF REFRACTION Calculate the angle of refraction Air Water n = .33 ?.8hE A ray of light traveling through air is incident on a smooth surface of water at an angle of 300 to the normal. Calculate the angle of refraction for the ray as it enters the water.
  11. Reflection and the Critical Angle Air 700 450 Water 810 480 , 900 Critical angle 490 500 Total internal reflection
