Hello Student,Please find the answer to your questionNote : nth line of Lyman series means electron jumping from (n + 1 )th orbit to 1st orbit.For an electron to revolve in (n + 1)th orbit.2&pi;r = (n + 1 )&lambda;&rArr; &lambda; = 2&pi; / (n + 1) x r = 2&pi; / (n + 1) [ 0.529 x 10-10] (n + 1)2 / Z&rArr; 1 / &lambda; = Z / 2&pi; [0.529 x 10-10] (n + 1) &hellip;(i)Also we know that when electron jumps from (n + 1)th orbit to 1st orbit1/ &lambda; = RZ2 [ 1 / 12 &ndash; 1 / (n + 1)2 = 1.09 x 107 Z2 [ 1 &ndash; 1 / (n + 1)2]From (i) and (ii)Z / 2&pi; (0.529 x 10-10) (n + 1) = 1. 09 x 107 Z2 [1 &ndash; 1 / (n + 1)2]On solving, we get n = 24ThanksNavjot KalraaskIITians Faculty
