WebThis angle is called the critical angle. Any angle larger than the critical angle will cause the light to be reflected back into the medium. This phenomena is called total internal reflection. Optical fibers are an example of using total internal reflection. The equation for the critical angle is: n1 sin θcritical = n2 sin ( 90.0 degrees) WebEnter the indices n1 and n2 and the angle of incidence α in degrees then press "Calculate Angles". Refractive Index in Medium 1: n 1 = 1.5 Refractive Index in Medium 2: n 2 = 1.3 Angle of Incidence: α = 25 ° …
WebThe angle of incidence when the angle of refraction is 90 o, and the ray changes from just refracting to total internal reflection, is called the critical angle. WebA numerical aperture of optical fibers calculator is included in this site and may be used to check the calculations in the following problems. Problem 1 let n = 1, n 1 = 1.46 and n 2 = 1.45 in the diagram of the optical fiber system above. Find a) the critical angle θ c at the core - cladding interface.
