Explanation:

the law of reflection refers to the reflection of light rays off smooth conducting surfaces , such as polished metal or metal coated glass mirror ,...

Answer 2

$\sf\red{Refractive \: index, \: also \: called \: index \: of \: refraction,}$

$\sf\red{measure \: of \: the \: bending \: of \: a \: ray \: of \: light \: when}$

$\sf\red{passing \: from \: one \: medium \: into \: another.}$

$\sf\red{Refractive \: index \: is \: also \: equal \: to \: the \: velocity \: of \: light \: c \: of \: a}$ $\sf\red{given \: wavelength \: in \: empty \: space \: divided}$

$\sf\red{by \: its \: velocity \: v \: in \: a \: substance, \: or \: n \: = \: c/v.}$
