The refractive index of diamond is 2.42. What is the meaning of this
statement?​

Answer 1

Answer:

Answer: When a ray of light travels from air into water obliquely, it bends towards the normal. This is because water is optically denser than air. On entering water, speed of light decreases and the light bends towards normal.
