Question

The refractive index of a medium is 1.7. What do you mean by this

statement.

The Refractive index of some medium given below : glass-1.5; what -1.33,

oil-1.2 In which of the medium is the speed of light maximum, minimum
​

Answer 1

Answer:

minimum

Explanation:

because the refractive index is more then it is called a denser medium

Answer 2

Answer:

Speed of light is minimum in this given medium whose refractive index is 1.7

and maximum in oil of refractive index is 1.2

Explanation:

Refractive index is high in any medium compare to other medium then the speed of light is slow in this medium than the other medium.

i.e,

Refractive index is inversely proportional to speed.
