Question

The refraction index of an anisotropic medium varies as $mu equals mu subscript 0 end subscript square root of left parenthesis x plus 1 right parenthesis end root comma text where end text 0 less or equal than x less or equal than a$ . A ray of light is incident at the origin just along y-axis (shown in figure). Find the equation of ray in the medium

$y = 2 \sqrt{x}$
$y = 4 \sqrt{x}$
$y = x$
$y = 3 \sqrt{x}$

The correct answer is: $y equals 2 square root of x$
