The maximum in the blackbody radiation intensity curve moves to shorter wavelength as temperature increases. The German physicist Wilhelm Wien demonstrated the relation to be max1/T . Later, Planck’s equation showed the maximum to be max=0.20hc/kt . In 1965, scientists researching problems in telecommunication discovered “background radiation” with maximum wavelength 1.05 mm (microwave region of the EM spectrum) throughout space. Estimate the temperature of space.
Use the data in Figure 4.8 to estimate the ratio of radiation intensity at 10,000 Å (infrared) to that at 5000 Å (visible) from a blackbody at 5000 K. How will this ratio change with increasing temperature? Explain how this change occurs.
Calculate the probability that an electron wi ll be found (a)between x= 0.1 and 0.2 nm, (b) between 4.9 and 5.2 nm in abox of length L = 10 nm when its wavefunction is 'If= (2/L) 112sin(2nx/L). Treat the wavefunction as a constant in the smallregion of interest and interpret 15 Vas llx.

The moment of inertia of a CH4 molecule is 5.27 × 10−47 kg m2. What is the minimum energy needed to start it rotating?
An electron is accelerated through an electric potential toa kinetic energy of 2.15 * 10-15 J. What is its characteristicwavelength? [Hint: Recall that the kinetic energy of a movingobject is E = 12mv2, where m is the mass of the object and n isthe speed of the object.]
In the Balmer spectrum of a hydrogen discharge lamp, the ratio of the intensities of the lines originating from levels n=3 and n=4 is 150/1. Estimate the temperature of the discharge gas, using the Boltzmann formula: Ni/Nj = (gi/gj)exp[-(Ei-Ej)/kT]. Where Ni is the originating energy level, gi is the degeneracy of the ith level (having principle quantum number n=i; so, for i = 1, g1 = 1, for i = 2, g2=4, for i = 3, g3= 9, etc.) and Ei is the energy of the ith level.
