1.	In hydrogen spectrum, the third line from the red end corresponds to which one of the following inter-orbit jumps of the electron for Bohr orbits in an atom of hydrogen ?
Answer» `5 rarr 2` `4 rarr 1` `2 rarr 5` `3 rarr 2` Solution :The lines at the red end BELONG to Balmer SERIES. These are obtained for jumps to n= 2 from outer ORBITS (1st line from n = 3, 2nd line from n = 4, 3ED line from n = 5)
