This can be solve using snell's law. snell's law equation is:

N1 / N2 = sin a2 / sin a1

where N1 is the index of refraction of the air which is equal to 1

N2 is the index of refraction of the medium

a2 is the angle of refraction

a1 is the incident angle

subsitute the given values

1 / N2 = 0.173 / 0.217

N2 = 1 (0.217 / 0.173)

N2 = 1.25 is the index of refraction
