The angle of the incidence () is the angle at which the light ray enters the material, with nbeing the11index of refraction for the first material (OpenStax, College 2017). The angle of refraction ()is the2angle that the light ray is refracted in the new material with nbeing the index of refraction for the new2material (OpenStax, College 2017). In this lab, the light ray travels from air into canola oil. Since canolaoil is more optically dense, the light ray will have a smaller angle of refraction when compared to theangle of incidence
