$\frac{sina}{sinb} = constant$

hope it may help u

Answer 2

$the \: ration \: of \: sine \: of \: angle \: of \: \\ incidence \: to \: the \: sine \: of \: angle \: of \: \\ refraction \: is \: constant \: of \: a \: same \\ color \: light \: and \: for \: a \: given \: pair \: \\ of \: mediam \\ \\ \frac{sin \: i}{sin \:r } = constant$
