Ahypthetical new mineral: unobtanium. unobtanium, when pure, is transparent and is very refractive. when the incident light ray strikes the surface at 45 degrees (sin 45 = 0.71), the refractive measures 12 degrees (sin 12 = 0.21)(all angles are measured from the normal). what is the refractive index of unobtanium?

Light from the sun reaches the earth in 8.3 minutes. the velocity is 3.00 x 10^8 m/s. how far is earth from the sun? i know how to get to d = (3 x 10^8 m/s)(498 sec). i just don't know how to get from there to the answer being 1.5 x 10^11 m.
