Monochromatic light falls on a vertical plate with two slits on a distance d 2.5 mm from each other. an interference pattern is observed on a screen distance 100 cm from a plate. somebody puts a glassy plate across one of the slits. the width of the plate is b- 10 m and the refraction coefficient n = 1.5. find the distance on which thte interference pattern shifts. in which direction does the pattern shifts?

Anybody wanna ? (picture included? )
