Question

If the refractive indices of water and alcohol are 1.33 and 1.36 respectively, which
of the two is optically denser medium?​

Answer 1

Answer:

The refractive index of alcohol is more than water, therefore, alcohol is optically denser medium.

Answer 2

Answer:

Alcohol is optically denser than water . This is because greater the refractive index more dense the liquid / material
