A spectroscopic instrument can resolve two nearby wavelengths λ and λ+ if λ/ is smaller than 8000.This is used to study the spectral lines of the Balmer series of hydrogen. Approximately how many lines will be resolved by the instrument?
The range of Balmer series is from 656.3nm to 365 nm. If the instrument can resolve up to 80000, then,

or, No. of wavelengths = 36
