Calculation Formula

n₁ sin(θ₁) = n₂ sin(θ₂)

Where:
n₁ = Refractive index of the initial medium (usually air, n₁ ≈ 1)
θ₁ = Incident angle
n₂ = Refractive index of the prism material
θ₂ = Refracted angle

How to Use the Calculator

  1. Enter the incident angle of the light in degrees.
  2. Enter the refractive index of the prism material.
  3. Click the "Calculate" button to compute the refracted angle.
  4. The result will be displayed in degrees.

Principle of Operation

The calculator uses Snell's Law to calculate the angle of refraction. Snell's Law states that the ratio of the sines of the angles of incidence and refraction is equal to the ratio of the refractive indices of the two media:

n₁ sin(θ₁) = n₂ sin(θ₂)

Where:

  • n₁ is the refractive index of the initial medium (usually air, n₁ ≈ 1)
  • θ₁ is the incident angle
  • n₂ is the refractive index of the prism material
  • θ₂ is the refracted angle
