Question: Use mathematical software to evaluate the Planck distribution at any temperature and wavelength or frequency, and evaluate integrals for the energy density of the radiation

Use mathematical software to evaluate the Planck at any temperature and wavelength or frequency, and evaluate integrals for the energy density of the radiation between any two wavelengths. Calculate the total energy density in the visible region (700 nm to 400 nm) for a black body at
(a) 1500 K, a typical operating temperature for globars,
(b) 2500 K, a typical operating temperature for tungsten filament lamps,
(c) 5800 K, the surface temperature of the Snn. What are the classical values at these temperatures?
