n=sinαsinβn equals the fraction with numerator sine alpha and denominator sine beta end-fraction
Observe the ray as it passes through the glass. Mark the exit point on the opposite side of the plate. n=sinαsinβn equals the fraction with numerator sine alpha
By measuring these angles, we can calculate the optical density of the glass. 2. Experimental Procedure n=sinαsinβn equals the fraction with numerator sine alpha
To measure the absolute refractive index of a glass plate using Snell's law. n=sinαsinβn equals the fraction with numerator sine alpha
