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

The ratio of the areas of the orbit for the second excited state to the first excited state for the hydrogen atom is

The energy needed to detach the electron of a hydrogen like ion in ground state is a system(a) what is the wavelength of the radiation emitted when the electron jumps from the first excited state to the ground state? (b) What is the radius of the orbit for this atom?

What is the ratio of radii of orbits corresponding to first excited state and ground state in hydrogen atom?

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.
