Hydrogen atom is exited from ground state to another state with principal quantum number equal to `4` Then the number of spectral linear in the emission spectra will be
A
`2`
B
`3`
C
`5`
D
`6`
Text Solution
Verified by Experts
The correct Answer is:
D
The possible number of the spectral lines is given `= (n (n - 1))/(2) = (4 (4 - 1))/(2) = 6`
