Which one among the following transitions of electron of hydrogen atom emits radiation of the shortest wavelength?

n = 2 to n = 1

n = 3 to n = 2

n = 4 to n = 3

n = 5 to n = 4

Explanation:

n = 2 to n = 1

The transition n2=∞ to n1=2 emits radiation of the lowest wavelength. This transition corresponds to maximum energy of emitted radiation. It is equal to the ionization energy and corresponds to the energy required when an electron is completely removed from ground state of hydrogen atom.
