The incident ray, reflected ray and the outward drawn normal are denoted by the unit vectors \(\overrightarrow a ,\overrightarrow b \space and\space \overrightarrow c \) respectively. Then choose the correct relation for these vectors.
1
\(\overrightarrow b = \overrightarrow a - \overrightarrow c \)
2
\(\overrightarrow b = \overrightarrow a - 2(\overrightarrow a .\overrightarrow c )\overrightarrow c \)
3
\(\overrightarrow b = \overrightarrow a + 2\overrightarrow c \)
4
\(\overrightarrow b = 2\overrightarrow a + \overrightarrow c \)
