Magical light family

Purpose & Scientific Principle

The carrier of electromagnetic radiation is photon, which does not need to rely on media for propagation. The propagation speed in vacuum is the speed of light. Electromagnetic radiation can be classified according to frequency, from low frequency to high frequency, including radio waves, microwaves, infrared rays, ultraviolet rays, X-rays and gamma rays.

How to Operate

The exhibition items show the characteristics and applications of different electromagnetic waves. The essence of light is an electromagnetic wave that can cause vision, and it is also a particle (photon). The carrier of electromagnetic radiation is photons, which do not need to rely on media for propagation. The propagation speed in vacuum is the speed of light. Electromagnetic waves can be classified according to frequency, from low frequency to high frequency, including radio waves, microwaves, infrared rays, ultraviolet rays, X-rays, gamma rays, etc. The electromagnetic wave characteristics are directly reflected through various models or experiments, allowing the audience to intuitively understand their characteristics and references. The graphic board focuses on the application of electromagnetic waves in the medical field, such as: gamma rays used as gamma knife for surgery; X-ray machines; ultraviolet disinfection, etc.

1. Understand light-related knowledge through touch screens, graphic boards, etc.

2. Press each button in the exhibition item to observe the characteristics of various lights.
