Question

What is the wavelength in nanometer of firstline in paschen series

Answer 1

Explanation:

The wavelength of the Paschen series is (820-1870) nm. - We need to arrange the wavelengths of the first lines of Lyman, Balmer and Paschen series in increasing order and from the data above mentioned the answer comes out to be \[{{\lambda }_{L}},{{\lambda }_{P}},{{\lambda }_{B}}\] in ascending order respectively.
