Problem

Match the temperature of a black body given in List-I with an appropriate statement in List-II, and choose the correct option. [Given: Wien’s constant as 2.9×10⁻³ m-K and hc/e=1.24×10⁻⁶ V-m] List-I: (P) 2000 K; (Q) 3000 K; (R) 5000 K; (S) 10000 K. List-II: (1) The radiation at peak wavelength can lead to emission of photoelectrons from a metal of work function 4 eV. (2) The radiation at peak wavelength is visible to human eye. (3) The radiation at peak emission wavelength will result in the widest central maximum of a single slit diffraction. (4) The power emitted per unit area is 1/16 of that emitted by a blackbody at temperature 6000 K. (5) The radiation at peak emission wavelength can be used to image human bones.
