Spectral radiance of a black body as defined by Planck's law: $$I\left(\lambda, T\right) = \frac{2{\pi}hc^2}{\lambda^5}\frac{1}{\exp\left(\displaystyle\frac{hc}{{\lambda}kT}\right) - 1}$$ where (h) is the Planck constant, (c) is the speed of light, and (k) is the Boltzmann constant.
Explore the behaviour of the spectral radiance by manipulating the black body temperature using the slider below!
The wavelength of the irradiance maximum is labelled inside the plot.
