DEMO advanced physics set: Geometrical Optics on the optical bench

Article no. 15560-88 | Type: Set

Delivery time: available

Principle

Real images are only created with converging lenses (convex lenses), whose focal lengths f are always positive. In contrast, concave or diverging lenses ( f < 0) produce only virtual images.

Benefits

  • Curriculum-relevant DEMO experiment in optics
  • Equivalence to the corresponding student experiment
  • Stable optical bench
  • Compact, simple construction

Tasks

  • Determination of the focal length in combination with a converging lens
