- Students will observe the affect of moving an object toward and away from a concave mirror.
- Students will graph the relationship between the object distance and the image distance from a mirror's focal point.
- Student will create an equation relating object distance to image distance.
- focal point
- virtual image
About the Lesson
Students focus on the relationship between the object and its image as the location and height of the object change. The focal point is movable to allow for further investigations. Students will vary the focal point of the concave mirror and observe how the image changes.
