Purpose: To use ray sightings to calculate the index of refraction of glass. Using your protractor, measure all four angles: the angle of incidence and the angle  We have prepared 2 exercises in which students can measure a value of a refractive index by themselves with use of a diffraction grating and a polarizer. Using the provided hexagon samples, measure the shift of beam for theree different andgle and determine the refractive index of the material. The distance  Refraction is an effect that occurs between transparent materials of different densities. The Refractive Index - n - of a medium is a measure for how much the  An online Calculator based on Snell's law to calculate angle of refraction of light optical properties of a medium is the index of refraction (or refractive index). Refractive index is often assumed to be 1.3 to 2.1 for organic material. Most often default values are used in calculation of particle sizes. If these values are not 

n 1 sinθ 1 = n 2 sinθ 2 Where, n 1 = Refractive Index of first medium n 2 = Refractive Index of second medium sinθ 1 = Angle of Incidence sinθ 2 = Angle of Refraction. Calculation of Refraction Index and Angle of Incidence is made easier using this Snell's Law Calculator. Formula 3 - Refractive Index (or Index of Refraction) n = c/η As the refractive index of a material increases, the greater the extent to which a light beam is deflected (or refracted) upon entering or leaving the material. A2A: The refractive index is a function of the both medium (material) through which a wave passes, and the frequency of the wave. I will give you three ways to calculate the index. 1. The index of refraction of a commercial material is usually spe To update the calculator, change the values in the colored boxes. Angle of incidence (θi) = Angle of refraction (θr) = Critical angle = none Total internal reflection: θi > critical angle Medium one (i)refractive index (ni) = Medium two (r)refractive index (nr) = Speed = 2.9979e8 ms-1 Speed = 1.9986e8 ms-1 Normal Interface The angle of refraction of light ray passing through Combining the above expression for velocity with the definition of index of refraction, we find a relationship between the wavelength = v /f in a medium and the wavelength 0 = c /f in vacuum: n r = index of refraction of the refractive medium This relationship between the angles of incidence and refraction and the indices of refraction of the two media is known as Snell's Law . Snell's law applies to the refraction of light in any situation, regardless of what the two media are. Snell's Law.
