Question

In optics, an object which has a higher refractive index is optically denser.

• A. True
• B. False

Answer 1

The correct option is A

True

One medium is said to be rarer and the other medium denser. when the refractive index of one medium 1 is greater than the other medium 2.
Suppose refractive index of air ${\mu }_a$ is $1$ and the refractive index of water ${\mu }_w$ is $1.33$ then water is optically denser medium than air.
