If $\hat{i}$ denotes a unit vector along incident light ray, $\hat{r}$ a unit vector along refracted ray into a medium of refractive index $\mu $ and $\hat{n}$ unit vector normal to boundary of medium directed towards incident medium, then law of refraction is

Question

Accepted Answer

$\hat{i}	imes \hat{n}=\mu (\hat{r}	imes \hat{n})$

Answer

$\hat{i}\,.\,\hat{n}=\mu (\hat{r}\,.\,\hat{n})$

Answer

$\hat{i}	imes \hat{n}=\mu (\hat{n}	imes \hat{r})$

Answer

$\mu (\hat{i}	imes \hat{n})=\hat{r}	imes \hat{n}$
