If an electron jumps from `1`st orbital to `3`rd orbital, than it will.

If an electron jumps from 1^(st) orbit to 3^(rd) orbit, then it will

The wavelength of radiation emitted is lamda_0 when an electron in a hydrogen atom jumps from 3rd to 2nd orbit . If the same hydrogen atom , the electron jumps from 4th orbit to 2nd orbit , then the wavelength of the emitted radiation will be

In hydrogen atom, an electron jumps from bigger orbit to smaller orbit, so that radius of smaller orbit is one-fourth of radius of bigger orbit. If speed of electron in bigger orbit was v,then speed in smaller orbit is

What happens if an electron jumps from E_2 orbit to E_3 orbit?
