Answer 2

Answer:

All of the above is the right answer. (Option d)

Explanation:

• When light strikes a boundary normally, it will not get refracted, whereas it passes normally to the other medium.
• If refraction does not take place when light passes through a medium, it means the refractive indices of the medium are the same.
• For refraction to occur, the light should travel from a denser to a rarer medium, or vice-versa.
• Also, if refraction doesn’t take place, then the angle of refraction should be less than the critical angle.
• If the incident ray is at 90 degrees, it shows that it is parallel to the normal and cannot bend away or towards it.
• If the light does not bend, then refraction does not occur.
• Therefore, the angle of incidence and angle of refraction are zero.
