A hypothetical atom has energy levels uniformly separated by 1.2 eV. At a temperature of 2000 K, what is the ratio of the number of atoms in the 13th excited state to the number in the 11th excited state?

Assertion: Two coherent sources S_1 and S_2 are placed in front of a screen as shown in figure. At point P, 10th order maxima is obtained. Then , 11th order maxima will be obtained above P. Reason: For 11th order maxima path difference should be more.
