Two stars a and b radiate maximum energy
WebThe peak wavelength for this star is at wavelength = 0.0029 / (1.2 x 10 4) m = (2.9/1.2) x 10-3-4 m = 2.4 x 10-7 m = 240 nm. The peak wavelength is ultraviolet, which our eyes can't detect. The star emits light in all of the visible range, but emits more blue light than red light. Therefore the star will appear to be a blue-white colour.
