Find the refractive index of a transparent medium in which light travels with a speed of 1.8×10^8m/s.Given that speed of light in vaccum is 3×10^8m/s?
index=speed light in vacumn/speedLightInMaterial
what is 3/1.8?
Answer
1.67
To find the refractive index of a transparent medium, you need to use the equation relating the speed of light in a vacuum (c) to the speed of light in the medium (v) and the refractive index (n) of the medium.
The formula is:
n = c / v
In this case, the speed of light in a vacuum is given as 3x10^8 m/s, and the speed of light in the medium is given as 1.8x10^8 m/s.
Plugging these values into the equation, we get:
n = (3x10^8 m/s) / (1.8x10^8 m/s)
Simplifying the expression, we get:
n = 1.667
Therefore, the refractive index of the transparent medium is approximately 1.667.
