1. Electromagnetism

This exhibition provides around forty accessible experiments for visitors to illustrate the fundamental principles of electromagnetism, grouped into various themes in the displays: the effects of an electrical current, electromagnetic forces, the alternative current, electrical engines, induction and auto-induction... 

 

 

2. Optical exhibition

This exhibition houses around forty experiments on the laws of reflection, total reflection and refraction.

These experiments are illustrated by devices that use lenses, prisms and mirrors. Visitors can therefore learn about how objects work, their qualities and their defects. Two very large lenses, one convergent, the other divergent, complete these experimental displays and allow visitors to look through the lenses at people on the other side. Further on, the formation of mirages is explained by demonstrating that, in certain circumstances, light can follow a curved trajectory. Finally, in the centre of the room, the burning mirrors experiment reveals the principle behind solar cookers.

 

 

3. Light room

Discovery space

In the first section, light is presented as part of the great family of electromagnetic waves. In particular, there is an interior setting, as seen through different frequencies (radio waves, micro waves, infrared, visible spectrum, ultraviolet, x-rays and gamma rays). There is an explanation of additive colour synthesis for younger visitors. There are also two areas all about infrared and ultraviolet.

The second section focuses on spectroscopy. White light is made up of several colours. The light emitted by an atom possesses the colours specific to that atom. 

The third section presents the undulating nature of light with diffraction and interference experiments.

The Historical space

It provides a chronological presentation of the great discoveries that have revealed the complex nature of light. It is divided into four themes around twenty displays presenting the major experiments that have marked each of these periods (the experiments of Newton on the composition of white light, Michelson's interferometer, the photoelectric effect discovered by Heinrich Hertz).

The Experimenting space

A variety of live experiments carried out to answer the simple but enormous question: what is light?
