    I have a conceptual doubt. pl help me clarify it:
    What will happen if angle of incidence on a glass slab is 0? will refraction take place, or reflection, or both?

    the incident light at any angle gets reflected and refracted ...it depends what you are looking for!

    At zero degrees, part of the light goes into the slab and part is reflected back at zero degrees (along the direction of incidence).
