Critical angle in optical fiber
WebThe critical angle is defined as the inverse sine of N2/N1, where N1 and N2 are the index of refraction (which is essentially a ratio of how fast light will travel through that … WebSolution: Given the indices for the means by which the ray passes, we use the formula. So, Critical angle is 1.064 rad. Example-2: A ray of light strikes from a medium with n = 1.67 on a surface of separation with the air with …
