how to find speed of light in medium
Answers
Answer:
As we know the distance between earth and sun which is equal to 149597871000.
And we know that light takes 8 minutes and 20 seconds which is equal to 500 seconds to travel from sun to earth.
As we know the formula of speed which is distance/time.
According to formula,
Speed =d/t
=149597871000/500
=299195742 m/s
Which is exactly equal to speed of light.
Therefore speed of light is 299195742m/s .

Step-by-step explanation:
If you can find a measured value of the refractive index n for the medium in a table, then it's just c/n where c is the vacuum speed. If it hasn't been measured, you can do it by measuring the amount of deviation of light undergoes when entering or leaving the medium and relating it to Snell's Law:
