The drawing shows an optical fiber that consists of a core made of flint glass(n flint= 1.667) surrounded by a cladding made of crown glass(n crown = 1.523). A beam of light enters the fiber from the air at an angle theta1 with respect to the normal. What is theta1 if the light strikes the core-cladding interface at the critical angle thetac?
