2. The speed of light in a certain plastic is 1.88*10^8 m/s. what is the index of refraction of plastic?
n = Vv/V = 3*10^8/1.88*10^8 = 1.596.
Vv = Velocity of light in a vacuum.
To find the index of refraction of the plastic, you can use the formula:
Index of refraction (n) = speed of light in vacuum (c) / speed of light in the material (v)
In this case, the speed of light in vacuum (c) is equal to 3.00 × 10^8 m/s. The given speed of light in the plastic (v) is 1.88 × 10^8 m/s.
Substituting these values into the formula:
n = c / v
n = (3.00 × 10^8 m/s) / (1.88 × 10^8 m/s)
n ≈ 1.60
Therefore, the index of refraction of the plastic is approximately 1.60.
To calculate the index of refraction of a material, you need to divide the speed of light in a vacuum by the speed of light in that material. The speed of light in a vacuum is approximately 3.00 x 10^8 m/s.
Given that the speed of light in the plastic is 1.88 x 10^8 m/s, you can use the following formula:
Index of Refraction (n) = Speed of Light in Vacuum / Speed of Light in the Material
n = (3.00 x 10^8 m/s) / (1.88 x 10^8 m/s)
Dividing these values, we have:
n ≈ 1.60
Therefore, the index of refraction of the plastic is approximately 1.60.
