240 nm wavelength of maximum emission.
The formula for this equation is λmax = b / T, where max is the peak wavelength of light given earlier, T is the absolute temperature of a black body, and b = 2.8977719 nm K is the Wien's displacement constant.
The emission wavelength, which comes from the fluorescent dyes used to create the item being measured, is known as the WaveLength. A radiation source with a certain excitation wavelength is what produces the fluorescent emission.
λmax = C / T
C is constant value 289777
t is 12200k
λmax = 240nm
