When the students focus the telescope model on a relatively
distant object in the second part of the experiment, it is
advisable for them to hold it with one hand and to focus with the
other. To avoid damage to the lenses, the teacher should have the
students attach the parts of the optical bench as tightly as
possible and to handle the lenses carefully. The use of a diaphragm
to limit the field of vision was avoided so that the model and the
experiment with it could be made as simple as possible.
- Multifunctional light box - All-in-one: Can be used for geometric optics on the table, colour mixing and on an optical bench
- Extension with others sets at anytime, no additional light sources needed, recognition value for students
How is an astronomical telescope constructed and how does it
work? Construct a model of an astronomical telescope and
investigate how its parts interact.
