Atomic Spectroscopy Experiment

Atomic spectroscopy is a series of specific frequencies of light emitted or absorbed by electrons in an atom as they transition between different energy levels. Due to the quantized energy levels of atoms, electrons can only occupy specific energy states and cannot exist at any energy value between these states. Therefore, each atom has its own unique spectral line, which is the "fingerprint" of the atom.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Scattering, in physics, refers to the change in the direction of particle motion caused by collision with another particle. The complete explanation of Raman scattering requires quantum mechanics theory, which can not only explain the frequency difference of scattered light, but also solve problems such as intensity and polarization. Electromagnetic waves are composed of electric and magnetic fields, which are perpendicular to each other and propagate in phase oscillation in space. This fluctuating electromagnetic field not only exhibits wave like properties, but also has particle like properties, namely wave particle duality. In particle form, the energy packet of electromagnetic waves is called a photon. When electromagnetic waves (light) encounter materials, if the frequency of the light wave matches the natural vibration frequency of the electrons in the material, the electrons will absorb the energy of these photons and convert it into their own vibrational motion. This process leads to the absorption and reflection characteristics of different materials towards light of different frequencies, resulting in the different colors we see. The electron vibration rate of each material is different, so they absorb special energy.
