5 A mica strip and a polysterene strip are fitted on the two slits of a double slit apparatus The thickness of the strips is 0 50 mm and the separation between the slits is 0 12 cm The refractive index of mica and polysterene are 1 58 and 1 55 respectively for the light of wavelength 590 nm which is used in the experiment The interference is observed on a screen a distance one meter away a What would be the fringe width b At what distance from the centre will the first maximum be Xocated
