Geometric Optics

= Objectives = After studying the material of this chapter, the student should be able to: 1. Distinguish between mirror reflection and diffuse reflection. 2. Draw a ray diagram and locate the position of the image produced by an object placed a specified distance from a plane mirror. State the characteristics of the image. 3. Distinguish between a convex and a concave mirror. Draw rays parallel to the principal axis and locate the position of the principal focal point of each type of spherical mirror. 4. Draw ray diagrams and locate the position of the image produced by an object placed a specified distance from a concave or convex mirror. State the characteristics of the image. 5. Use the mirror equations and the sign conventions to determine the position, magnification and size of the image produced by an object placed a specified distance from a spherical mirror. 6. State Snell's law and use this law to predict the path of a light ray as it travels from one medium into another. Explain what is meant by the index of refraction of a medium. 7. Explain what is meant by total internal reflection. Use Snell's law to determine the critical angle as light travels from a medium of higher index of refraction into a medium of lower index of refraction. 8. Distinguish between a convex and a concave lens. Draw rays parallel to the principal axis and locate the position of the principal focal points for each type of thin lens. 9. Draw ray diagrams and locate the position of the image produced by an object placed a specified distance from either type of thin lens. State the characteristics of the image. 10. Use the thin lens equations and the sign conventions to determine the position, magnification, and size of the image produced by an object placed a specified distance from a concave or convex lens.
