The ratio of the wave lengths of the first line in the Lyman series of the spectrum of Hydrogen atom and the first line in the Balmer series of the spectrum of He^(+) is
The ratio of the wave lengths of the first line in the Lyman series of the spectrum of Hydorgen atom and the first line in the Balmer series of the spectrum of He^(+) is
(A) Atoms of each element are stable and emit characteristic spectrum (R): The spectrum provides useful information about the atomic structure.
Ramu R: The visible spectrum is a part of the electromagnetic spectrum. Laxman (L) : The electromagnetic spectrum is a part of the visible spectrum.
A certain transition in H-spectrum from an axcited state to ground state in one (or) more steps gives rise to total 10 lines. How many of these belongs to UV-spectrum.
