Question

A transparent medium A floats on another transparent medium B. When a ray of light travels obliquely from A to B the refracted ray bends away from the normal. Which of these two media A or B are optically denser and why?

Answer 1

Transparent medium a is optically denser.

Since light is bending away from the normal medium B have refractive less than the medium A.

Denser mediums tends to have more refractive index
