How can I find error in refractive index if glass prism if the value of my n is 1.5094
To find the error in the refractive index of a glass prism, you need to compare the measured refractive index value with the accepted or known value. Here's how you can do it:
1. Determine the accepted refractive index value: The accepted value for the refractive index of a glass prism can usually be found in reference tables or provided by the manufacturer. Let's assume the accepted value is 1.5.
2. Calculate the absolute error: The absolute error is the difference between the measured value and the accepted value. In this case, the absolute error would be:
Absolute Error = |Measured Value - Accepted Value|
Absolute Error = |1.5094 - 1.5| = 0.0094
3. Calculate the relative error: The relative error, also known as the percentage error, is the ratio of the absolute error to the accepted value, multiplied by 100 to express it as a percentage. The formula for relative error is:
Relative Error = (Absolute Error / Accepted Value) * 100
Relative Error = (0.0094 / 1.5) * 100 ≈ 0.63%
Therefore, the error in the refractive index of the glass prism is approximately 0.63%.
