Calculate the wavelength of radiation emitted producing a line in the Lyman series ,when an electron falls from fourth stationary level in hydrogen atom `(R_(H) = 1.1 xx 10^(7)m^(-1))`

Text Solution

Verified by Experts

`(1)/(lamda)=R((1)/(n_(1)^(2))-(1)/(n_(2)^(2)))`
`=1.1xx10^(7)((1)/(1^(2))-(1)/(4^(2)))`
`=969.6xx10^(-10)` metre
`thereforelamda=969.4`Ã…
