Lesson Plan: Image Production Using Lenses Physics
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to define the focal length of a lens, describing how light passing through convex and concave lenses forms real and virtual images.
Objectives
Students will be able to
- recognize that a real image is produced by converging light rays,
- recognize that a virtual image is produced by diverging light rays,
- recognize that concave lenses only produce virtual images,
- recognize that for convex lenses incident parallel light rays produce a real image of an object at a greater distance from the lens than the focal length of the lens,
- recognize that for convex lenses incident parallel light rays produce a virtual image of an object at a lesser distance from the lens than the focal length of the lens,
- recognize that the image produced by a convex lens is smaller than the object for objects at distances from the lens greater than twice the focal length of the lens,
- recognize that the image produced by a convex lens is larger than the object for objects at distances from the lens less than twice the focal length of the lens,
- recognize that the image produced by a convex lens is the same size as the object for objects at distances from the lens equal to twice the focal length of the lens,
- recognize that a real image produced by a converging lens is inverted relative to the object imaged,
- recognize that a virtual image produced by a convex lens or a concave lens has the same vertical orientation as the object imaged.
Prerequisites
Students should already be familiar with
- definitions of the locations of focal points for convex and concave lenses.
Exclusions
Students will not cover
- the use of the formula .
