Question

If 9.9eV energy is supplied toH atom the no of spectral lines emitted are

Answer 1

Answer:

If 9.9 eV energy is supplied to H atom the no. of spectral lines emitted is equal to 0.

The energy difference between ground state and first excited state of electron of H atom is 13.6−3.4=10.2eV.

When energy less than this is applied, no emission occurs.
