MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A ray of light travels through air until it strikes the interface between the air and another medium. The incident ray makes an angle of 01 = 34.0 with the normal, as shown in the figure below. Upon passage into the second medium, the ray is refracted, emerging from the interface at an angle 02 with respect to the normal. Air Second medium (a) Suppose that the second medium is fluorite. What is the angle of refraction, 02 (in degrees)? (Enter your answer to at least one decimal place.) (b) Suppose that the second medium is ice. What is the angle of refraction, 02, in this case (in degrees)? (Enter your answer to at least one decimal place.) (c) Finally, suppose that the second medium is ethyl alcohol. What is the angle of refraction, 02, in this case (in degrees)? (Enter your answer to at least one decimal place.)
