Star A is a blackbody that has a power vs. wavelength curve as intensity shown in the two diagrams to the right. Now consider Star B, which is the same size as Star- A but is hotter. On the top graph, sketch what it's blackbody curve will look like in reference to Star A. Now consider Star C, which is at the same temperatur e as Star- A but has a larger radius. On the bottom...
