At the 111 — n2 interface part of the light reflects, part of it refracts. Answer the following questions: IIIIIII H131L3 d=5mm a] [4 pt] What is the angle of reflection {at the H1 — n3 interface}? h} [4 pt] What is the angle of refraction [at the 111 — n2 interface]? cl [4 pt] What is the minimum value of 113 that will result in total internal reflection at the[at the n; — n3 interface}? d} [4 pt] What distance does the transmitted wave travel while moving from the 111 — in:interface to the 112 — n3 interface? e] [4 pt] How long does the beam take {from part d] to travel that distance?
