Answer :
n = sin i / sin r
sin i -- incident ray angle
sin r -- refracted ray angle
n -- refractive index
so the answer is 1.49 (3s.f.)
*Refractive Index cannot go below 1
sin i -- incident ray angle
sin r -- refracted ray angle
n -- refractive index
so the answer is 1.49 (3s.f.)
*Refractive Index cannot go below 1
