The velocity of light in a metal is 1.25 x 10^8 m/s. What is d refractive index of the metal.
To find the refractive index of the metal, we can use the formula:
refractive index (n) = speed of light in vacuum (c) / speed of light in the material (v)
Given that the velocity of light in the metal (v) is 1.25 x 10^8 m/s, we need to know the speed of light in vacuum (c).
The speed of light in vacuum is a well-known constant, approximately equal to 3 x 10^8 m/s.
Therefore, we can substitute these values into the formula:
n = c / v
n = (3 x 10^8 m/s) / (1.25 x 10^8 m/s)
Simplifying this expression, we get:
n ≈ 2.4
So, the refractive index of the metal is approximately 2.4.
