What is the wavelength of light emitted when the electron in a hydrogen atom undergoes transition from an energy level with n = 5 to an energy level with n = 3 ?

Explanation

Formulae :
`barv=(1)/(lamda)=R[(1)/(n_(1)^(2))-(1)/(n_(2)^(2))]`
`=1,09,677[(1)/(3^(2))-(1)/(5^(2))]`
`=1,09,677[(25-9)/(9xx25)]`
`lamda=(1)/(barv)=(1)/(7799.25)=(1.2821xx10^(-4))cm`
`=12821Å`
`R=1,09,677cm^(-1)`
`n_(1)=3`
`n_(2)=3`
`n_(2)=5`
`barv=7799.25cm^(-1)`
