An electron in an excited state of hydrogen atom absorbs 2.5 times the energy needed to unbound the electron and moves with a wavelength of 5.416 Å `(h = 6.6xx10^(-34) `Js`)`
The electron was originally in

A

n = 3

B

a=4

C

n=5

D

n=2

Text Solution

Verified by Experts

The correct Answer is:
