Question

what is optical denser and optical rare

Answer 1

Hello friend!!
Rajdeep here...

Optically denser mediums are those in which speed of light is slow (as compared to optically rarer medium).

Speed of light is faster in optically rarer medium.

For example, Kerosene is optically denser than water.
Glass and water are optically denser than air.

Thanks!!

Hello mate ,

When comparing two mediums, in which light travels slow compared to other medium is called denser medium and in which light travels fast compared to another medium then the medium is called rarer medium
