4. To determine: The wavelength of peak radiation. From Wein's displacement law, the expression of peak wavelength is λmax=bT where λmax is peak wavelength, b is the Wein's constant and T is temperature The value of Wein's constant is 2.898×10-3 m.K. The temperature is 2.73 K. Substitute these values in equation (1) λmax=2.898×10-3 m.K2.73 Kλmax=1×10-3 mλmax=0.001 m The wavelength of peak radiation is 0.001 m. Correct option: (a)
