Light travels from medium A into medium B with an angle of
incidence of 18.7 degrees. Medium A has a refractive index of
1.67 and medium B has a refractive index of 1.34.
(a) Determine the angle of refraction in medium B.
(b) If medium A is used as the core of an optical fibre and
medium B is used as the cladding, calculate the critical angle for
the fibre.
