Angle of Refraction Calculator: Unlock the Secrets of Light Refraction

Calculate the Angle of Refraction

The refractive index of the medium from which light is entering (e.g., Air, Vacuum).
The angle at which light strikes the interface, measured from the normal (0 < θ₁ < 90 degrees).
The refractive index of the medium into which light is entering (e.g., Water, Glass).

Utilize our Angle of Refraction Calculator to effortlessly apply Snell's Law. Quickly determine how light bends as it transitions between different mediums. Understand the relationship between refractive index, incident angle, and the resulting angle of refraction with this essential physics tool.

Formula:

The Angle of Refraction is calculated using Snell's Law, which describes the relationship between the angles of incidence and refraction, and the refractive indices of the two mediums:

n₁ sin(θ₁) = n₂ sin(θ₂)

To find the Angle of Refraction (θ₂), the formula is rearranged to:

θ₂ = arcsin((n₁ sin(θ₁)) / n₂)

  • n₁: Refractive index of the first medium (incident medium)
  • θ₁: Angle of incidence (angle between the incident ray and the normal)
  • n₂: Refractive index of the second medium (refracting medium)
  • θ₂: Angle of refraction (angle between the refracted ray and the normal)
