(a) The Lyman series in hydrogen is the transition from energy levels n = 2, 3, 4, ... to the ground state n = 1. The energy levels are given by 13.60 eV En n- (i) What is the second longest wavelength in nm of the Lyman series? (ii) What is the series limit of the Lyman series? [1 eV = 1.602 x 1019 J, h = 6.626 × 10-34 J.s, c = 3 × 10° m.s] %3D Two emission lines have wavelengts A and + A2, respectively, where AA <<2. Show that the angular separation A0 in a grating spectrometer is given aproximately by (b) A0 = V(d/m)-2 where d is the grating constant and m is the order at which the lines are observed.

1) The Lyman series of lines in the emission spectrum of hydrogen corresponds to transitions from various excited states to the n1 = 1 orbit. Calculate the wavelength (in nm) of the energy line (n = 11) in the Lyman series to five significant figures. (RH = 109677.57 cm-1). Think about where this is in the spectrum. 2) What is the wavelength, (in angstroms, A) of an electron (m = 9.11 X 10-31 kg) moving at 7.80 X 105 m/sec. (h= 6.626 X 10-34 Js)

In hydrogen atom, an electron undergoes transition from 3rd excited state to the first excited state and then to the ground state. Identify the spectral series to which these transitions belong. (ii) Find out the ratio of the wavelengths of the emitted radiations in the two cases.
