Calculate the refractive index for each trial using the formula
Observe the ray as it passes through the glass. Mark the exit point on the opposite side of the plate. Calculate the refractive index for each trial using
). 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: Calculate the refractive index for each trial using
To measure the absolute refractive index of a glass plate using Snell's law. Calculate the refractive index for each trial using
Repeat the measurements for different angles of incidence to ensure accuracy. 3. Data Analysis
