The speed of light of a plastic is 1.4x10^8. What is the index of refraction in the plastic?

To find the index of refraction in the plastic, you need to use the formula:
Index of Refraction = speed of light in vacuum / speed of light in the material
In this case, the speed of light in vacuum is a well-known value, which is approximately 3 x 10^8 meters per second.
The speed of light in the plastic material is given as 1.4 x 10^8 meters per second.
Now, substitute these values into the formula:
Index of Refraction = (3 x 10^8) / (1.4 x 10^8)
To simplify, divide the numerator and denominator separately:
Index of Refraction = 3 / 1.4
Dividing these values gives the index of refraction in the plastic material:
Index of Refraction ≈ 2.14
