A stars spectrum emits more radiation with a wavelength of 700.0 nm than with any other wavelength.If the star is 9.78 ly from Earth and its radius is 7.20 \times 108 m, what will an Earth-based observer measure for this stars intensity? Stars are nearly perfect blackbodies. (Note: ly stands for light- years.) W/m2
