Plank's distribution law gives the blackbody emissive power (amount of radiation energy emitted) as a function of temperature and wave length:

Where C1 = 3.742 x 108 w?m 4/m2, C2 = 1.439 x 104 ?mK, T is the temperature in degrees K, and A. is the wave length in pm. Make a 3-D plot (shown in the figure) of E as a function of ? (0.1 A 10 ?m) and T for 100 T 2000K. Use a logarithmic scale for ?. This can be done with the command: set (gca, 'xscale' , ' log' ).
