WebMay 20, 2024 · The formula is given by n = 1 sin ( C), n is the refractive index of the denser medium, C is the critical angle. From this formula, it seems to be that we are substituting the angle of refraction as the angle of incidence, therefore sin ( 90) sin ( C), but why can we do this? Why not sin ( C) sin ( 90).
