Three Flat Layers of Transparent Material Are Stacked Upon One

Question 58

Multiple Choice

Three flat layers of transparent material are stacked upon one another.The top layer has index of refraction n1,the middle has n2 and the bottom one has n3.If n1 > n2 > n3,and if a ray of light strikes the top layer at an angle of incidence Three flat layers of transparent material are stacked upon one another.The top layer has index of refraction n<sub>1</sub>,the middle has n<sub>2</sub> and the bottom one has n<sub>3</sub>.If n<sub>1</sub> > n<sub>2</sub> > n<sub>3</sub>,and if a ray of light strikes the top layer at an angle of incidence ,in which layer is the angle of refraction the greatest? A) the top layer B) the middle layer C) the bottom layer D) Once the ray enters the touching layers,the angle of refraction remains constant.
