The critical angle for light going from medium ' x ' to medium ' Y ' is . The speed of light in medium ' x ' is ' V _ x '. The speed of light in medium ' Y ' is

Options

  1. AV _ x
  2. BV _ x
  3. CV _ x
  4. DV _ x

Correct answer

D. V _ x

Step-by-step solution

Refractive index of ' x ' w.r.t. ' y ' is y _ x = 1 Also _y n_x= V_y V_x = 1 V _ y = V _ x
