Question: The x-ray spectrometer on board a satellite measures the wavelength at the maximum intensity emitted by a particular star to be m = 82.8

The x-ray spectrometer on board a satellite measures the wavelength at the maximum intensity emitted by a particular star to be λ_m = 82.8 nm. Assuming that the star radiates like a blackbody,

(a) Compute the star’s surface temperature.

(b) What is the ratio of the intensity radiated at λ = 70 nm and at λ = 100 nm to that radiated at λ_m?
