for an electron in H-atom the frequency of photon for transition between levels 1 and 2 is v. The photon frequency for transition between levels 2 and 3 is closet to

Options

A. `0.2v`
B. `0.1v`
C. v
D. A is true,B is true

Answer

a

Explanation

Frequency of Lyman series is given by,
`V=RC[1/1^2-1/n^2]n=2`
`V=RC[1/1^2-1/((2))^2)=RC(1/1-1/4)`
`v=RC[3/4]`
`RC=4/4V`
For transition between levels 2and 3 is ,
`V_(1)=CR[(1)/2^(2)-(1)/3^(2)]`
=CR`[(1)/(4)-(1)/(9)]`
`CR[(5)/(36]`)
implies `V_(1)=((4)/(3)V)((5)/(36))``impliesV_(1)=(5)/(27)V`
`=0.18V`
`cong0.2V`
