Compared with the peak wavelength given off by the Sun, what is the peak wavelength given off by a hotter star?

A hotter star has a shorter peak wavelength, according to Wien’s law: as temperature increases, the wavelength of peak emission decreases. Shorter-wavelength light has higher energy, so the peak emission is both shorter in wavelength and higher in energy. The correct choice is “shorter in wavelength and higher in energy.”
