What is the ratio of minimum to maximum wavelength of radiation emitted by electron when it jump from as higher state to ground state in `Li^(2+)` ion ?

A

`(1)/(4)`

B

`(8)/(9)`

C

`(3)/(4)`

D

`(1)/(9)`

Text Solution

Verified by Experts

The correct Answer is:
C

What is the ratio of …………..
`(((1)/(lambda_(max))))/(((1)/(lambda_(min))))=(R(3)^(2)[(1)/(1^(2))-(1)/(2^(2))])/(R(3)^(2)[(1)/(1^(2))-(1)/(oo^(2))]) = 3//4`
`:. (lambda_(min))/(lambda_(max)) = (3)/(4)`
