Refraction

Refraction

Objective: Determine the index of refraction for a given substance and verify Snell's Law.

Video Tutorial:

Data Collection Techniques/ Strategies: Don't forget to measure the angles of incidence and refraction to their individual normal line. Keep in mind: the higher the index of refraction, the higher the density of a material.

Analysis Questions: 1. How does the index of refraction (density) affect light as it enters a given material? 2. How would you express the relationship between n1 and n2 when light moves from a less dense material to a more dense material? 3. If light travels from a material with a large n into a material with a smaller n, how does the light bend?

Graphical Analysis: No graphical analysis is necessary for this lab. The data points that determine the slope of the line and area underneath are both insignificant to this lab.

Percent Difference or Error: No percent difference or error is necessary for this lab. [|Sample Lab for Refraction.doc] media type="file" key="jing_video-_refraction.swf" align="center" width="360" height="270"
