Answer:

0 degree is the correct✔✔✔ answer

Explanation:

mark me as brilliant

Answer 2

Answer:

90

Explanation:

• If a ray hits the surface of  the glass normal or at a 90 degree angle to the surface, the ray passes through without changing direction.
• In this case the angles of incidence and  refraction are always zero.
• When  light is refracted, the incident  rays are diffracted.
• A refracted  ray is bent toward or away from the normal.
• If the incident  ray is less than 900 degrees, it means that it is parallel to the normal and  cannot move away from or near the normal.
• If the light beam is not diffracted, there will be no refraction.

Hence, the answer is 90 degree.
