The critical angle for light going from medium ' $x$ ' to medium ' $Y$ ' is $θ$ . The speed of light in medium ' $x$ ' is ' $V_{x}$ '. The speed of light in medium ' $Y$ ' is

Options:

Answer:

Solution:

Refractive index of ' $x$ ' w.r.t. ' $y$ ' is $y_{x} = \frac{1}{sin θ}$ Also $_{y} n_{x} = \frac{V _{y}}{V _{x}} = \frac{1}{s i n θ}$ $∴ V_{y} = \frac{V _{x}}{sin θ}$
