For example a pane of window glass has a thickness that may be stated by the manufacturer but which should be measured to ensure accurate calculation of the refractive indexStep 2 Send light from a point light source through the object. Therefore it can be understood that for a medium of higher refractive index the speed of light in that medium will be slower. 2What is the critical angle where refraction becomes total internal reflection when passing from a material with index of refraction n1 447 to another material with index of refraction n2 207.
Refractive Index Index of Refraction is a value calculated from the ratio of the speed of light in a vacuum to that in a second medium of greater density.
Furthermore refractive index values may be significantly higher in the case of infrared waves. Then apply variation principles delta T0 find the path your light beam takes. N is the refractive index of the material. We can also use wavelengths to calculate refractive index.
