![]() If you look into a glass window, sometimes you can see your reflection in the window, as well as objects behind it. Often, some waves are reflected and some waves are refracted. If the object is transparent, light waves can be refracted as they pass through it. When waves strike an object, several thingsĬan happen. ![]() What is the maximum distance between the lens and the object? Calculate Object Distance If you looked through a convex lens withĪ focal length of 15 cm and saw a real, inverted, enlarged image, ◗ The cornea and the lens focus light ontoġ2. ◗ A concave lens is thinner in the middle and ◗ A convex lens is thicker in the middle thanĭepends on the distance of the object from Image formation by a concave mirror, describe the image formedīy a light source placed at the focal point of a convex lens. Think Critically If image formation by a convex lens is similar to Explain how lenses are used to correct vision problems.ġ1. Describe the image formed by a concave lens.ġ0. Compare the image of an object less than one focal length from aĬonvex lens with the image of an object more than two focalĩ. MAIN Idea Sketch light rays as they pass through a convex lens andĨ.
