Question

For the first two lines of paschen series, identify the value of n1 and n2. Calculate the wave number values for these lines.

Answer 1

Answer:

  wavenumber v1=5331.569cm^-1

wavenumber v1=7799.324cm^-1

Step-by-step explanation:

Paschen sires starts from n=3

 First line n1=4;

 Second line n2=5;

wavenumber  v1=Rydbergconstant×[(1÷n^2)-(1÷n1^2)]

                       =109678×[(1÷9)-(1÷16)]

                       =5331.569cm^-1

wavenumber v2=Rydbergconstant×[(1÷n^2)-(1÷n2^2)]

                        =109678×[(1÷9)-(1÷25)]

                       =7799.324cm^-1
