Light travels a distance $x$ in time $t_1$ in air and $10x$ in time $t_2$ in another denser medium. What is the critical angle for this medium?
- A$\sin^{-1}\left(\frac{10 t_1}{t_2}\right)$
- B$\sin^{-1}\left(\frac{t_2}{t_1}\right)$
- C$\sin^{-1}\left(\frac{10 t_2}{t_1}\right)$
- D$\sin^{-1}\left(\frac{t_1}{10 t_2}\right)$
