1 Is the may bent when it passes into the lens perpen- dicular to the flat surface of the lens? D Is the may bent when it passes out of the lens perpendicular to the curved surface of the lens? By rotating the Ray Table, set the angle of inci- dence to each of the settings shown in Table 4.1 on the following page. For each angle of incidence. measure the angle of refraction (Refraction, ). Repeat the measurement with the incident may striking from the opposite side of the normal (Re- fraction )
