How many different wavelengths may be observed in the spectrum form a hydrogen sample, if the atoms are excited to third excited state?

A

`3`

B

`4`

C

`5`

D

`6`

Text Solution

Verified by Experts

The correct Answer is:
D
N=`(n(n-1))/2`
For third excited state,n=4
thereforeN=`(4(4-1))/2=6`

Hydrogen atom in its ground state is excited by means of a monochromatic radiation of wavelength 970.6 Å . Different wavelengths are possible in the spectrum. After absorbing the energy of radiation, hydrogen atom goes to the excited state. After 10^(-8) s, the hydrogen atom will come to the ground state by emitting the absorbed energy.
