Calculate the refractive index for each trial using the formula

. Typically, for standard glass, the result should be approximately . 4. Conclusion Calculate the refractive index for each trial using

) of a medium shows how many times the speed of light in a vacuum ( ) is greater than its speed in the medium ( Conclusion ) of a medium shows how many

n=sinαsinβn equals the fraction with numerator sine alpha and denominator sine beta end-fraction a piece of cardboard

). According to the , the ratio of the sine of the angle of incidence ( ) to the sine of the angle of refraction ( ) is constant for two given media:

Place the glass plate on a sheet of paper and trace its outline.

A glass plate with parallel edges (or a prism), a piece of cardboard, pins (or a laser pointer), a ruler, a protractor, and a pencil. 1. Theoretical Background The refractive index (
