(Solution) - The element sodium can emit light at two wavelengths -(2025 Original AI-Free Solution)
Paper Details
The element sodium can emit light at two wavelengths, ?1 = 589.10 nm and ?2 = 589.59 nm. Light from sodium is being used in a Michelson interferometer (Figure). Through what distance must mirror M2 be moved if the shift in the fringe pattern for one wavelength is to be 1.00fringe more than the shift in the fringe pattern for the other wavelength?
