what is the relation between Refractive Index of a medium and the speed of light in that medium
Answers
Answer:
refractive index is inversely propotional to speed of light in that medium
Answer:
Hi! This is your Answer
Explanation:
Explanation:
This question asks us to consider the relationship between velocity and index of refraction of a medium. If we think back to the definition of index of refraction, we know that it is defined by the ratio of the velocity of light in a vacuum and the velocity of light in some other medium.
n=cv
n is the index of refraction, c is the speed of light in a vacuum, and v is the speed of light in the new medium.
We can see that n and v are inversely proportional, meaning that the higher the n, the lower the velocity. As the light moved from air (n =1) to glass (n = 1.5), the n increased, and thus the velocity must decrease because the speed of light in a vacuum is constant.
