 * Notes**


 * 19.1 Mirrors**

__Objectives__:

1. Describe the law of reflection. 2. Describe how a plane mirror produces an image. 3. Define real and virtual images and relate them to converging and diverging light rays. 4. Describe the physical characteristics of plane, concave, and convex mirrors and distinguish between the types of images they form.


 * 19.2 Lenses**

__Objectives__:

1. Explain what causes light to refract. 2. Define index of refraction. 3. Describe the physical characteristics of concave and convex lenses an distinguish between the types of images they form. 4. Describe total internal reflection and explain its relationship to the critical angle.


 * 19.3 Optical Instruments**

__Objectives__:

1. Distinguish between how reflecting and refracting telescopes form images. 2. Explain how cameras regulate and focus light to form images. 3. Describe how light travels in a compound microscope to produce an enlarged image.


 * 19.4 The Eye and Vision**

__Objectives__:

1. Name the main parts of the eye and describe their functions. 2. Name common vision problems, identify their causes, and explain how they can be corrected.
