The Wien displacement law states that the wavelength maximum in micrometers for blackbody radiation is A T = 2.9 x 10 where Tis the temperature in kelvins. Calculate the wavelength maximum for a blackbody that has been heated to a 10000 K Wavelength = jum b. 6000 K Wavelength= um c. 2000 K Wavelength = um d. 1000 K Wavelength = um
For blackbody radiation obeying Planck's distribution law show by direct computation that the energy fluctuation for radiation in a volume V in the spectral interval is given by Einstein's fluctuation formula: Please show all steps (u,v + du) ((AE)2) = V (hvu, + envz uz) dv where u,dv is the corresponding energy density. Show that just the first term would result from Wien's distribution law whereas just the second term would result from the Rayleigh-Jeans distribution law.
Show how Plank’s radiation law (a) Yields Wien’s displacement law. (b) Reduces to Raylegh-Jean formula for large wavelengths. Gives Stephan-Boltzmann law.
3. Correspondince between classical and quantum mechanics (a) Assuming the Hamilton operator HV(c) show that This problem can be solved very similarly to what we had done in class for 2). Note that for this you may want to expand the potential energy operator V() in terms of the position operator x as V( a1+ After having dealt with the first few terms of the expansion, you probably will realize that it may be useful to find a general expression...
