Lesson: Drawing Ray Diagrams for Concave Mirrors Science • Third Year of Preparatory School

Students will be able to

• show, using diagrams, that parallel incident rays on a spherical mirror are reflected through the focal point of the mirror,
• show, using diagrams, that incident rays that pass through the focal point are reflected parallel to the optical axis,
• show, using diagrams, that incident rays that pass through the center of curvature are reflected back through the center of curvature,
• recall that a real image is an image that can be projected onto a screen,
• recall that a virtual image is an image that cannot be projected onto a screen,
• draw ray diagrams to determine the position of an image produced by reflection off a spherical mirror,
• identify, from ray diagrams of reflection off spherical mirrors, whether the image is real or virtual,
• identify, from ray diagrams of reflection off spherical mirrors, whether the image is magnified or reduced in size,
• identify, from ray diagrams of reflection off spherical mirrors, whether the image is inverted or upright.
