You Are Experimentally Determining the Critical Angle for a Novel

question 60

Multiple Choice

You are experimentally determining the critical angle for a novel transparent solid whose index of refraction is less than that of water (n=1.33) but greater than that of air (n=1.00) .Your experimental method involves work underwater in which you observe whether there is any transmitted ray at the water/solid interface as you vary the angle of incidence on the solid surface.When your device reaches an incident angle of 53 degrees you find that the transmitted ray vanishes.What is the index of refraction for this new solid?

• A) 1.16
• B) 0.57
• C) 1.06
• D) 0.53
