The frequency of the `H_(beta)`-line of the Balmer series for hydrogen is

A

`2upsilon_(0)Hz`

B

`4upsilon_(0)Hz`

C

`(upsilon_(0)//2)Hz`

D

`(upsilon_(0)//4)Hz`

Text Solution

Verified by Experts

The correct Answer is:
B
`upsilon=Z^(2)Rc[(1)/(n_(1)^(2))-(1)/(n_(2)^(2))]`
For hydrogen atom, Z = 11
`(1)/(lambda.)=121R(3)/(4)`
`(lambda.)/(lambda)=(3R)/(4)xx(4)/(121Rxx3)=(1)/(121) rArr lambda.=(lambda)/(121)=(1210)/(121)=10Å`
