Virtual images with a concave mirror

Principle

A concave mirror produces upright, virtual images of objects which lie within the simple focal length. The closer the object to the focal point, the larger the image.

Benefits

• minimal preparation time
• light-intense halogen lamp
• easy teaching by using the demo board for demonstration
• ideal complement to analog student experiments by directly comparable devices

Tasks

Draw the light beams as completely as you can. Draw a second image arrow closer to the focal point and proceed analogously. Draw the light paths in front of the mirror, and then extend the reflected beams to their intersection points. Draw the image arrows.
