A simple method for measuring the refractive index of liquid is described with the help of detailed theory. A laser beam suffers a lateral displacement due to refraction while passing through a liquid. This displacement of laser beam from its incident direction is measured for different angles of incidence to find the refractive indices of oils that are commonly used in the laboratory.
