Question

1. A huge trough has liquids of refractive indices 1, 2, ... , as shown in the figure. The thickness of the layers is 1, 2, ... , respectively. If a screw is kept at the bottom of the trough, it will experience a shift in its depth due to the bending of light in the different media. (a) Find its apparent depth (h′) if the depth of the trough is h. (b) Find h′ if 1 = 2 =⋯= . *
