Can anyone explain in simple words for what is rarer and denser medium

[sarnian]

Hello mahesrajan

Rarer is about being non-common (a rare item is an item that is not found or available in big quantities).

Denser is about content quantity (a dense item is rather heavy for it's size)

Dear sarnian
The medium which has higher refractive index is called optically denser and the medium which has smaller refractive index is called optically rarer. Is it corrct explnation

Dear mahesrajan

If you wanted the optical description you should have mentioned that.
I used the general term for the words denser and rarer!
Thanks for the update!

Dear Mahesrajan

I already understood that from your post #3, but the question lacked that information, and my reply #2 referred to the question, not to your post #3. Learns you to post questions properly and full in detail. I - and many with me - do our best to help others with their questions, but we all fail the ability to mind-read ! :)
