Homework Statement



A double-slit experiment is performed with light of wavelength 558.0 nm. The bright interference fringes are spaced 1.84 mm apart on the viewing screen. What will the fringe spacing be if the light is changed to a wavelength of 335.0 nm?

Homework Equations



d= [tex]\frac{\lambda * L}{spacing}[/tex]

The Attempt at a Solution


so our assumption is that everything stays constant while only the wavelength changes and the fringe spacing..right?? i am unable to think ahead of this point ..pls. help

nevermind i made a silly error while trying to set up a ration btw the 2 wavelengths and distances
