When light falls perpendicularly or normally on the surface of a glass slab, it goes straight. There is no bending of ray of light on entering the glass slab or coming out of it. In this case angle of incidence and angle of refraction is zero......

it is displaced and deviated because even in the experiment you are to measure the displacement from the original path and the angle of deviation
