When electrons are de-exciting from nth orbit of hydrogen atoms to ground state, 15 spectral lines are formed. The shortest wavelength among these will be

A

`11/900R`

B

`36/(35R)`

C

`35/36R`

D

`35/(36R)`

Text Solution

Verified by Experts

The correct Answer is:
B
`(n(n-1))/2=15 rArr n=6`
`1/(lambda)=Rxx1^(2)[1/(1^(2))-1/(6^(2))]=Rxx35/36`
`lambda=36/(35R)`
