Question

what is the deser medium and rarer medium ?​

Answer 1

Answer:

When fog is dense, you can't see through it. And if someone calls you dense, they think nothing can get into your thick skull. Dense comes from the Latin densus which means thick and cloudy. In general, the word means packed tight and gives the sense that something is difficult to get through.

A rarer medium can be best defined as a medium where light travels faster. ... And if you are studying light refraction then in terms of physics, The medium in which the light changes its path and bends towards the normal is the denser medium and the medium in which the light bends away from the normal is the rarer medium.
