A ray of light travels from air to water to glass and again from glass to air. Refractive index of water with respect to air is ' x^ , glass with respect to water is ' y^ and air with respect to glass is 'z'. Which one of the following is correct?

Options

  1. Axz=v
  2. Bz = x
  3. Cxyz =1
  4. Dx y= z

Correct answer

C. xyz =1

Step-by-step solution

X = V _ a V _ , Y = V _ w V _ g , Z = V _ g V _ a XYZ =1
