It is only possible if light enters another medium with an angle other then 90.
WHen it does so then some part of light enters the medium first and it slows down first while the other part enter after a while and slows down later. This time gap .For much better understanding see... http://www.YouTube.com/watch?v=Tyzci1qTVL8
It is called refraction.
The substance's index of refraction isSpeed of light in vacuum / Speed of light in the substance
No
The index of refraction of a substance is(The speed of light in vacuum) divided by (the speed of light in the substance) .
Speed of light in air (which has an index of refraction of 1) is 3 * 10^8 m/s. So divide the speed of light by the index of refraction of the new medium to obtain the speed of light in that medium. Hope I helped!!
It is the refraction of light.
It is the refraction of light.
Refraction.
Refraction.
This is caused by a change in the speed of light .
Refraction
It is called refraction.
This sounds like refraction.
index of refraction ( or refractive index)
The substance's index of refraction isSpeed of light in vacuum / Speed of light in the substance
light undergoes refraction when the matter changes the speed of light
No
