Question

Parth · Answer

in this question you’ve to use the concept of the circle of illuminance A = Angle at which total internal reflection is occurring, in this case, it is given by sin(A) = 1/mu. mu = 4/3; A = 48.5903 degrees ; in this case percentage of light escaped = [1 – cos(A)]/2 which gives 0.169281 which is nearly 16.92% or 17 %
