    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    The critical angle for a piece of quartz is 37.3 degrees when the quartz is in air. If the piece of quartz is instead immersed in a transparent liquid with index of refraction n = 1.31, what is the angle of refraction in the liquid for a light ray incident at 21 degrees?

    -the answer is not:

    16.4 degrees

    51.48 degrees
