This tool calculates the index of refraction using the speed of light in different mediums.
How to Use
To use the refractive index calculator, follow these steps:
- Enter the refractive index of the first medium (n1).
- Enter the refractive index of the second medium (n2).
- Enter the angle of incidence (θ1) in degrees.
- Click the “Calculate” button to see the results.
Explanation
This calculator uses Snell’s Law of Refraction to compute the angle of refraction (θ2). Snell’s Law states that
n1 * sin(θ1) = n2 * sin(θ2)
Therefore,
sin(θ2) = (n1 / n2) * sin(θ1)
The angle of refraction θ2 is then computed from sin(θ2).
Note: If the calculated sin(θ2) value is greater than 1, total internal reflection occurs, and θ2 is not defined.
Limitations
– Ensure the refractive indices are positive values. Negative or zero values are invalid. – The incident angle should be between 0 and 90 degrees. – The calculator does not account for extraordinary refraction phenomena such as birefringence.
