Calculate the wavelength for the transition from n = 4 to n = 2, and state the name given to the spectroscopic series to which t
finlep [7]

Answer:

The wavelength for the transition from n = 4 to n = 2 is<u> 486nm</u> and the name  name given to the spectroscopic series belongs to <u>The Balmer series.</u>

Explanation

lets calculate -

Rydberg equation-   \frac{1}{\pi } =R(\frac{1}{n_1^2} -\frac{1}{n_2^2})

where ,\pi is wavelength , R is Rydberg constant ( 1.097\times10^7), n_1 and n_2are the quantum numbers of the energy levels. (where n_1=2 , n_2=4)

Now putting the given values in the equation,

                \frac{1}{\pi }=1.097\times10^7\times(\frac{1}{2^2} -\frac{1}{4^2} )=2056875m^-^1

    Wavelength \pi =\frac{1}{2056875}

             =4.86\times10^-^7 = 486nm

<u>    Therefore , the wavelength is 486nm and it belongs to The Balmer series.</u>
