TESTING INVESTIGATION: INDEX OF REFRACTION

AP PHYSICS 2

Essential Knowledge 6.E.3

6.E.3: When light travels across a boundary from one transparent material to another, the speed of propagation changes.

At a non-normal incident angle, the path of the light ray bends closer to the perpendicular in the optically slower substance.

This is called refraction.

• LO 6.E.3.2: The student is able to plan data collection strategies as well as perform data analysis and evaluation of the evidence for finding the relationship between the angle of incidence and the angle of refraction for light crossing boundaries from one transparent material to another (Snell’s law).
