Statement-1: The wavelength of any radiation belonging to any series (other than Lyman series) is greater than the wavelength of any radiation belonging to Lyman series for all the hydrogen like atoms.Statement-2: Energy difference between two successive energy levels decreases as ‘n’ increases.

A
Statement-1 is true, statement-2 is true and statement-2 is correct explanation for statement-1.
B
Statement-1 is true, statement-2 is true and statement-2 is NOT the correct explanation for statement-1.
C
Statement-1 is true, statement-2 is false.
D
Statement-1 is false, statement-2 is true.

Correct explanation is

$|E_{1} - E_{n_{1}}| > |E_{2} - E_{n_{2}}| > |E_{3} - E_{n_{3}}| > |E_{4} - E_{n_{4}}| > |E_{5} - E_{n_{5}}|$

$n_{1} = 2, 3, 4 . . . . . . n_{2} = 3, 4, 5 . . . . . . n_{3} = 4, 5, 6 . . . . . . n_{4} = 5, 6, 7 . . . . . . n_{5} = 6, 7, 8 . . . . . . .$
