alleryAt an interface, nonzero incidence equals refraction. The two indices are
AEqual to each other
BIn a ratio of 3:2
CIn a ratio of 1:2
DIn a ratio of 2:1
Answer & Solution
Correct answer: A. Equal to each other
Equal nonzero incidence and refraction angles give a relative refractive index of one, so the indices are equal.
