An electron in `H` atom makes a transition from `n = 3 to n = 1`. The recoil momentum of the `H` atom will be

In hydrogen atom, electron makes transition from n = 4 to n = 1 level. Recoil momentum of the H atom will be

An electron in hydrogen atom makes a transition from n=n1 to n=n2 .The time period of the electron in the initial state is eight times that in the final state.The possible values of n1 and n2 are:

In a hydrogen atom , the electron atom makes a transition from n = 2 to n = 1 . The magnetic field produced by the circulating electron at the nucleus

A hydrogen atom emits a photon corresponding to an electron transition from n = 5 to n = 1 . The recoil speed of hydrogen atom is almost (mass of proton ~~1.6 xx 10^(-27) kg) .

Calculate the change in magnetic dipole moment when the electron in a H- atom makes a transition from the n=4 orbit to the n=3 orbit. Suppose that the atoms is in a magnetic field of induction. Calculate the change in energy when it makes the same transition and the corresponding change in frequency of the emitted photon due to the magnetic field.

An electron in a hydrogen atom makes a transition from n_(1) to n_(2) . If the time period of electron in the initial state is eight times that in the final state then Find the ratio n_(1)/n_(2)

The electron in a hydrogen atom makes a transition from n=n_(1) to n=n_(2) state. The time period of the electron in the initial state (n_(1)) is eigh times that in the final state (n_(2)) . The possible values of n_(1) and n_(2) are

In the hydrogen atom, an electron makes a transition from n=2 to n=1. The magnetic field produced by the circulating electron at the nucleus
