Young's double$-$slit experiment is performed with $590-$nm light and a distance of $2\mathrm{.}00$ m between the slits and the screen. The tenth interference minimum is observed $7\mathrm{.}25$ mm from the central maximum. Determine the spacing of the slits $($in mm$).$ x A minimum intensity occurs whenever the difference in path lengths for light traveling from the two slits is the wavelength multiplied by one half more than an integer. mm $($b$)$ What If$?$ What are the smallest and largest wavelengths of visible light that will also produce interference minima at this location?
