Lesson: Drawing Ray Diagrams for Convex Lenses Science • Third Year of Preparatory School

Students will be able to

• recognize that parallel incident rays are converged to a point by a convex lens,
• recall that the point that parallel incident rays are converged to by a convex lens is known as the focal point,
• draw ray diagrams to determine the position of an image formed by a convex lens,
• identify from ray diagrams of convex lenses whether the image of an object is real or virtual,
• identify from ray diagrams of convex lenses whether the image of an object is magnified or reduced in size,
• identify from ray diagrams of convex lenses whether the image of an object is inverted or upright.
