Question
The expression for refractive index is given bySelect one:a. N = v/cb. N = c/vc. N = 1/cvd. N = cv
Solution
The correct answer is:
b. N = c/v
The refractive index (N) of a medium is defined as the speed of light in vacuum (c) divided by the speed of light in the medium (v). Therefore, the formula for refractive index is N = c/v.
