1. (a) Look up the definition of the index of refraction on p. 334 (b) Table 18 is on page 708
2. Use table 18 to find the index of refraction for each material. Use the first value given for sapphire.
4. Use Snell's law (p. 335) for this one.
6. Use the equation on p. 339 here; look up the index of refraction for glycerol. Remember how to use the inverse trig functions on your calculator?

1. Use 2nd equation on p 350 to find locations of objects or images with lenses or mirrors.
3. (a) see #1 (b) Use 1st equation on p. 350 to find height of images or objects if locations are known.
5. Equation for simple magnifier (magnifying glass) is on p. 351.
7. Microscope equation is on p. 352, near the top.
12. (a) Look at the ray diagrams on p. 348 and see which type image is found on the same side of the lens as the object. (b) see #1 (c) see #3(b)
