MCAT Physics Question — Refractive Index
- Dec 24, 2014
- MCAT Blog, MCAT Physics, MCAT Question of the Day
Using the diagram below, what is the refractive index of glass?
This question is testing your understanding of optics, specifically refraction. To solve this problem, you must use Snell’s Law, nairsinΘair = nglasssinΘglass, where n is the index of refraction and Θ is the angle between the line normal to the surface and the incident light.
Thus, nglass = nairsinΘair/sinΘglass
nglass = (1)sin60o/sin30o
making A the correct answer.
