physics

$\sin^{-1} \left(\frac{t_2}{t_1} \right)$

$\sin^{-1} \left(\frac{10t_2}{t_1} \right)$

$\sin^{-1} \left(\frac{t_1}{10t_2} \right)$

$\sin^{-1} \left(\frac{10t_1}{t_2} \right)$

Explanation

To find the critical angle for the medium, we need to determine the refractive index of the medium relative to air. $\\$ Given: $\\$ • Light travels a distance $x$ in time $t_1$ in air. $\\$ • Light travels a distance $10x$
