Three flat layers of transparent material are stacked upon one another.The top layer has index of refraction n₁,the middle n₂ and the bottom one n₃.If n₁ n₂ n₃,and a ray of light in air strikes the top layer,at which surface given can total internal reflection occur first? A)the top surface B)the surface between materials with indices n₁ and n₂ C)the surface between materials with indices n₂ and n₃ D)Total internal reflection cannot occur at any of these surfaces.

Question

Three flat layers of transparent material are stacked upon one another.The top layer has index of refraction n₁,the middle n₂ and the bottom one n₃.If n₁ > n₂ > n₃,and a ray of light in air strikes the top layer,at which surface given can total internal reflection occur first? A)the top surface B)the surface between materials with indices n₁ and n₂ C)the surface between materials with indices n₂ and n₃ D)Total internal reflection cannot occur at any of these surfaces.
