Experiment on goniometry experiments

This set allows a simple approach to direction finding and has the essential settings and functions allowing quality experiments to be carried out.

Subjects discussed :
- Adjustment and calibration of a goniometer
- Characterization of a network or a prism
- Study of line spectra
- Minimum deviation of a prism
- Reading a vernier

Principles and objectives:
A goniometer allows the characterization of light sources by identifying the positioning of the emission lines. Thus, using a chart, it is possible to determine the chemical species that make up the observed light source.
The Balmer series designates the series of hydrogen lines, each corresponding to the energy transition from a higher state to the level 2 state. In the visible, it is possible to distinguish the first 4 lines: Hα, line red @656 nm, Hβ, turquoise line @486 nm, Hγ, blue line @434 nm and Hδ, violet line @410 nm
