experiments
• 1 - Light and shadow

With the laser and the LED of the student lamp as well as the associated worksheet, the formation of shadows as a stitching optics is investigated.

• 2 - Law of reflection

### experiment "Law of reflection"

The law of reflection is discovered with the laser of the student lamp on the measuring table.

• 3 - Curved mirrors

### experiment "Curved mirrors"

The reflection of a parallel beam of light is reflected convex spherically, concavely spherically and concave parabolically on the surfaces. The test is carried out as a stitching optics.

• 4 - Snell’s law of refraction

### experiment "Snell’s law of refraction"

The transition of light from air to glass is investigated. Snellius's law of refraction is discovered and the refractive index of air in glass is determined experimentally.

• 5 - Fermat’s principle

### experiment "Fermat’s principle"

In this experiment, the principle of Fermat with a stitching optics is discovered.

• 6 - Refraction and total internal reflection in water

### experiment "Refraction and total internal reflection in water"

The transition of light from water to air is investigated. The refractive index of water and the limit angle of the total reflection are determined.

• 7 - Exercises: Refraction

### experiment "Exercises: Refraction "

The refraction of light in different bodies is constructed in a stitching optic and then controlled with the laser of the student lamp.

• 8 - Paths of light through lenses

### experiment "Paths of light through lenses"

The beam paths through convex and concave lenses are examined as stitching optics.

• 9 - Focal point of a converging lens

### experiment "Focal point of a converging lens "

In two partial tests, the focal points of a cut-collecting lens with the stitching optics are first determined. The focal point of a lens on the optical bench is then measured.

• 10 - Formation of image by a converging lens

### experiment "Formation of image by a converging lens"

Through a collecting lens (f=50mm) the formation of the centimeter scale printed on the screen is observed.

• 11 - Lens equation

### experiment "Lens equation"

The lens equation is derived from the imaging scale and experimentally confirmed with a scale slide.

• 12 - Optical instruments - Terrestrial telescopes

### experiment "Optical instruments - Terrestrial telescopes"

The optical device will be presented as part of a student lecture with experiment. In addition to the general functionality, the use of prisms is explained and the importance of magnification number and objective diameter is discussed.

• 13 - Optical instruments - Astronomical telescopes

### experiment "Optical instruments - Astronomical telescopes"

The optical device will be presented as part of a student lecture with experiment. In addition to the general functionality, the function of the eyepiece and lens are explained and a comparison with the reflector telescope is made.

• 14 - Optical instruments - Projectors

### experiment "Optical instruments - Projectors"

The optical device will be presented as part of a student lecture with experiment. In addition to the general functionality, the function of the condenser is explained and the orientation of the projection is discussed.

• 15 - Optical instruments - Optical microscopes

### experiment "Optical instruments - Optical microscopes"

The optical device will be presented as part of a student lecture with experiment. In addition to the general functionality, the function of the eyepiece and objective are explained and the magnification is discussed.

• 16 - Light and colour

### experiment "Light and colour"

The light of the LED is broken down into its spectral colors with a prism. The test is carried out as stitching optics.
