QCM7015 Theoretical Exercise 1: Blackbody Constants: h = 6.626 x 1024 s; k= 1.381 x 10 JK"; C = 2.998 x 10 ms? Temperatures: 3000 K, 4000 K, 5000 K and 6000 K Wavelength, 2m = 20, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900, 2000 = Demonstrate graphically Planck's distribution law of the radiation emitted by a blackbody to show the effects of wavelength and temperature on blackbody radiation by plotting (1) Energy density versus Wavelength and (ii) Energy density versus Frequency for various temperatures. First make a table with the following columns: Wavelengthm, Frequency/s', Energy density at 3000 K, 4000 K, 5000 K and 6000 K. On the same plots, show how the energy density varies with wavelength and frequency using the Rayleigh-Jeans (R-J) equation for T = 6000 K only. For the R-J plot, use the x-axis values to the point where the energy density is highest in the Planck's distribution law plot (i.e. start with the highest a value for Energy density vs Wavelength and lowest v value for Energy Density vs Frequency). Use Excel for the calculations and plots
