"1. Construct representing on a piece of paper a half-circle a mirror whose inside surface is silvered (see Fig. 19.23). Suppose you place a small lightbulb on the axis halfway between point R in Fig. 19.23 and the surface of the mirror. Now carefully draw three different rays that leave the lightbulb, reflect from the mirror, and move away. Would this mirror and light be useful for a headlight on your car? Explain. (Ignore the colored ray in Fig.19.23.) FIG. 19.23 Axis- R x=?
