Door Medium

Which medium will speed of light be greater? vacuum, atmosphere on Mars, Ind Ocean at 200 ft, door of a vault?

This is a question in physical science class, last part of question refers to the door of a bank vault.

Think of which medium will provide the least resistance to the light to propigate through.

The speed of light in a vacuum is the maximum speed light will travel, in any other medium, it is slower. The amount the speed changed is based on how “optically dense” the material is. There is a numbering system to designate this, called the index of refraction (symbolized “n”).
Each substance has its own index of refraction,
a vacuum is 1.000000000000,
air is almost 1, just slightly over,
water is must higher, and so on.

If you know the index of refraction, you can calculate the speed of light by dividing the speed of light in a vacuum by the index of refraction,
v = c / n
