Q.
In the adjacent figure, equation of refracted ray is
A) $y = \sqrt{3}x + 1$
B) $y + \sqrt{3}x - 3 = 0$
C) $\sqrt{3}x + y - \sqrt{3} = 0$
D) None of these
Explanation
(c)
Slope of refracted ray is
$- \tan{60{^\circ}} = - \sqrt{3}$
It passes through (1, 0)
$\therefore\ y = - \sqrt{3}(x - 1)$
$\Rightarrow \ \sqrt{3}x + y - \sqrt{3} = 0$
