Answer:

Yes, the diagram is correct as when the light falls perpendicular on the glass slab, it goes without any refraction. The angle of Incidence here is 0° because it is the angle made by the Incident Ray and the Normal (90°) at the point of Incidence and as the Incident coming perpendicular or lie on the normal itself, the angle of incidence is 0°
