temperature. If the peak occurs at a long wavelength, the star is cooler than a star that gives off most of its light (peaks) at a short wavelength. For example, if Star $\mathrm{E}$ and Star $\mathrm{F}$ are the same size and temperature, they will have identical blackbody curves. However, if Star $\mathrm{F}$ is the same size as Star $\mathrm{E}$, but is cooler, then its energy output is less at all wavelengths and the peak occurs at a longer wavelength (toward the red end of the spectrum). Figure 2a Figure 2b Figure 2c USE FIGURE 2B to answer Questions 6-9. Assume Stars E and F are the same size. 6) Which star gives off more red light? Explain your reasoning. 7) Which star gives off more blue light? Explain your reasoning. 8) Which star looks redder? Explain your reasoning.
