What is the shortest wavelength in the Paschen series of spectral lines?
Step 1: Formula for the calculation of wavelength
Here, is the wavelength
is Rydberg constant,
=1,2........ , and = ,.……
The first five series of lines that correspond to are known as the Lyman, Balmer, Paschen, Bracket, and Pfund series, respectively.
Step 2: Calculating the shortest wavelength for paschen series
For the Paschen series,
.
Hence, the shortest wavelength is .
