- Mark submitted by Author:
Have a little read: ... David Urlanda Physics Lab Report Refraction of Light - Air into Glass Purpose: When light travels through different mediums, it is being refracted. The purpose of this lab is to test Snell's law of refraction. Hypothesis: The angles of refraction that I predicted from the angle of incidences by using Snell's Law are below on the predicted angle Column. To obtain these values I used the index of refraction of crown glass because it is more likely close to the glass (plexiglass) that we are using. Angle of Incidence 0° 10° 20° 30° 40° 50° 60° Predicted angle of refraction 0 6.56° 13.0° 19.2° 25.02° 30.27° 34.74° Variables and Controls: Independent Variable: The angle of the light coming from the ray box or the angle of incidence Dependent Variable: The angle of refraction on the plexiglass. Controls: The mediums where light travels (air and plexiglass). Materials: - ray box - plexiglass - white paper, protractor and pencil Procedure: 1. I folded the blank paper into four equal parts. Then drew two intersecting lines perpendicular to each other. 2. Using the protractor I
