- 6) A glass plate with an index of refraction of 1.57 is immersed in an oil having a refractive index of 1.40. What is the critical angle? and which path is the appropriate path for the light to travel for total internal reflection to occur? From oil to glass, or glass to oil? Explain.A laser illuminates a screen with two small holes drilled in it very close together. The lightemitted from the holes shines on a distant screen. What will be seen on the distant screen?a. A bright central dot surrounded by dimmer concentric circles.b. Two bright dots.c. A series of a few dots that are widely separated.d. A series of many dots that are very close together.Can water waves be reflected and refracted? Give examples. Does Huygens’s principle apply to water waves? Explain.
- 5.) see photo for detailsUnder what conditions can you see a rainbow in the sky? Try to explain the basics of how rainbows work.9. Consider a planar interface with the refractive index n, in the lefthand side and n2 in the right- hand side. Explain what are the boundary conditions needed to be satisfied and how the Snell's rule ni sin(0;) = n2 sin(0;) is derived from the boundary conditions.
