JEE Question 2007 Paper I

The largest wavelength in the ultraviolet region of the hydrogen spectrum is 122 nm. The smallest wavelength in the infrared region of the hydrogen spectrum (to the nearest integer) is

(A) 802 nm (B) 823 nm (C) 1882 nm (D) 1648 nm

Sol: Ans [B]



1/122 = R*(1 - (1/4));
(1/λ) = ((1/9)-(1/∞))
From the two equations R = 823nm

HC Verma looks to be a very popular book in India. And this plan sounds great. Very impressive indeed. I am a college sophomore with a dual major in Physics and Mathematics @ University of California, Santa Barbara. By the way, i came across these excellent physics flash cards. Its also a great initiative by the FunnelBrain team. Amazing!!
