# Class set Optics 2.0

## Klassensatz Optik 2.0

Thanks to the unique multifunctional student lamp, this class set for six learning groups can be used for free experiments even in rooms that are not darkened. All ray trajectories of geometric optics can be examined directly in the booklet, and the results can be saved afterwards.

Special features
Certified student lamp with laser (class 1) and LED with very low heat generation
High quality optical body with prism for color decomposition
Universal mirrors: parabolic concave, spherical concave, spherical convex, plane
With experiment on Fermat's principle
Completeness verifiable at a glance

In the accompanying material
Each experiment with material list, 3D instructions, implementation instructions, evaluation and tips
Measurement sheet with angle scale enables direct measurement of angle of incidence and angle of reflection

Art. no. 47545

experiments
• 1 - Light and shadow

### experiment "Light and shadow"

Using the laser and the LED of the student lamp as well as the associated worksheet, the creation of shadows is examined on the worksheet.

• 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"

A parallel light beam is reflected on convex spherical, concave spherical and concave parabolic surfaces. The experiment is done on the worksheet.

• 4 - Snell`s law of refraction

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

The transition of light from air into glass is investigated. Snell`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, Fermat's principle is discovered.

• 6 - Exercises in light refraction

### experiment "Exercises in light refraction"

The refraction of light in different bodies is constructed on the worksheet and then verified with the laser of the student's lamp.

• 7 - Paths of light through lenses

### experiment "Paths of light through lenses"

The ray paths through convex and concave lenses are examined on the worksheet.

• 8 - Focal point of a converging lens

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

In two sub-experiments, the focal point of a converging lens is first determined using the worksheet. Then the focal point of a lens on the optical bench is measured.

• 9 - Light and Color

### experiment "Light and Color"

The light from the LED is split into its spectral colors using a prism.
