The wavelengths of prominent lines in visible range observed in mercury are 405 nm, 436 nm, 492 nm, 546 nm, 577 nm, and 623 nm. If the light emitted by a mercury lamp passes through a double slit, what is the smallest slit separation that will allow to observe an interference pattern for all six lines? O 623 nm O 405 nmConsider a screenshot from the simulation we have briefly discussed in class during the introduction of the topic on diffraction gratings.
