241.5 nm via Wein's Displacement Law


Wein's Law is #lambda=b/T# where b is Wein's constant of proportionality equal to #2.89×10^(−3) m K#

This answer is valid so long as the intensity is plotted as a function of wavelength. If frequency or some other variable is used on the horizontal axis, the peak will be at a different wavelength
