Hydrogen spectrum consists of four lines in the visible range: 410 nm, 434 nm, 486 nm, and 656 nm. If the light emitted by a hydrogen lamp passes through a diffraction grating, what is the smallest slit separation that will allow you to observing an interference pattern for all four lines? O 656 nm O 410 nm
