Use Figure 20.9 to find the brightness (relative to its maximum brightness) of a type II supernova 100 days after the time of maximum light.

FIGURE 20.9 The Brightness of a Typical Type II Supernova Before and After the Supernova Reaches Maximum Brightness After 100 days, the supernova is only a few percent as bright as it was at maximum brightness.
