Snell's Law Calculator is a physics/math calculator to find the angle of refraction, angle of incidence, refractive index of the medium containing the incident ray, or refractive index of the medium containing the transmitted ray fast and easy. Features: - Instant calculation - Results are copyable to other apps - Formulas are included as reference - Supports up to 16 decimal places - Supports various units for each input Snell's law (also known as Snell–Descartes law and the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air. Snell's Law describes the behavior of light when it encounters media having varying refractive indices. A refractive index is an expression of the ratio of the speed of light in a given medium versus its speed in a vacuum (with a refractive index of 1). It's important to note that light's speed doesn't actually change; it's more accurate to say that light takes a longer trip, with more delays, at full speed in glass than in air. There is no critical angle when the refractive index of the medium containing the incident ray is less than the medium with the transmitted ray. Snell's law describes how a ray refracts at an interface between materials. Snell's Law formula: n₁ * sin (θ₁) = n₂ * sin (θ₂) Where: n₁: Indices of refraction of Medium 1, dimensionless θ₁: Angle of incidence, in radians n₂: Indices of refraction of Medium 2, dimensionless θ₂: Angle of transmission, in radians Thanks for your support, and do visit nitrio.com for more apps for your iOS devices.
