Light travels a distance x in time t_1 in air and 10 x in time t_2 in another denser medium. What is the critical angle for this medium?
Light travels a distance $\displaystyle x$ in time $\displaystyle t_1$ in air and $\displaystyle 10 x$ in time $\displaystyle t_2$ in another denser medium. What is the critical angle for this medium?
Official answer
From NTA’s final answer key for this paper.
