Exiting ray make withthe outside surface of the cladding

Reference no: EM13645797

A light ray in the core (n = 1.40) of a cylindrical optical fibretravels at an angle θ1= 49.0 degrees with respect to the axisof the fibre. A ray is transmitted through the cladding (n = 1.20)and into the air. What angle θ2 does the exiting ray make withthe outside surface of the cladding?
