Question

1. The phenomenon due to which a ray of light __________
from its path while travelling
from one optical medium to another optical
medium is called refraction,
2. The incident ray, the _______ ray
and normal lie in the same plane during refraction,
3. When a ray of light strikes the surface of separation of two optical media __________ it does not suffer any refraction
4. The ratio of velocity of light in vacuum to the velocity of light in a given media is called _____
5. when a Ray of light travels from an optically denser medium to an optically denser medium the angle of incidence is always_____then the angle of refraction.​

Answer 1

Answer:

1. deflects
2. reflected
3. perpendicular to the surface
4. refractive index
5. question is confusing you have used optical denser 2 times

hope my answer is helpful
