The ratio of areas within the electron orbits for the first excited state to the ground state for hydrogen atom is

`16 : 1`

`18 : 1`

`4 : 1`

`2 : 1`

Text Solution

Find the wavelength of electron orbiting in the first excited state of hydrogen atom.

Assertion: In the duration electron jumps from fist excited state to ground state in a stationary isolated hydrogen atom, angular momentum of the electron about the nucleus is conserved. Reason: As the electron jumps from first excited state to ground state, in a hydrogen atom, the electrostatic force on electron is always directed twoards the nucleus.
