Principle

The purpose of the experiment is the investigation of the
refraction of light on passing from glass into air and the
determination of the angle of refraction for several given values
of angle of incidence. In addition to the deepening of their
understanding of the law of refraction, the students’ experimental
skills are exercised in terms of the precise and careful execution
of the experiment, adjustment and reading of the angles with the
optical disk. Following the experiment, it is possible to discuss
the reversability of light and thus to theoretically substantiate
the experiment.

Benefits


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



Tasks

Why do objects in water appear to be raised? Investigate the
behaviour of narrow light beams on passing from glass into air and
measure the angle of refraction as a function of the angle of
incidence.
