Modern-Physics Area

The twentieth century is the great discovery of physics, but also the physical concept of the great revolutionary era. During this period the development of physics is called modern physics, and before that physics is called classical physics. "X-ray", "natural radiation", "electronic" three major physical discovery, opened the 20th century physics discovery era prelude. Quantum mechanics and relativity form two important cornerstones of modern physics.

The Invisible Energy - Infrared Radiation

The Invisible Energy - Infrared Radiation

Three camera capture and project the images of the audience onto three screens in the front. The left is the image of "visible light," the right the "near infrared" image, and the center the "middle infrared" image. Which wave length is the most familiar to the naked eye? Which wave length needs an external light source so that people in the front will appear? Which wave length is the strongest radiation wave length emanated by the human body? In the middle infrared image in the front, why are there some "gangster-like" figures wearing sunglasses? Move an acrylic plate over and see if the middle infrared ray could pass. Light up the three lights on the exhibition panel. The visible light is clear, but which light bulb is missing in the middle infrared image? Why?

A Colorful World of Optical Spectra

A Colorful World of Optical Spectra

Move the cylindrical spectrometer. Point it to the light sources in the front in turn, and observe the spectra of each light source from the view finder. What differences can you see from the spectra? Some light sources reveal obvious and bright colorful lines while others display a continuum of colors without lines. Some only show a singular color. Where do these differences come from? Observe the shapes and specifications of the light sources. What conclusions can you deduce in terms of the light emission of these sources?

Electro-optic Effect - Little Heroes of Electricity

Electro-optic Effect - Little Heroes of Electricity

Please stand on the markers in front of the three screens and wave your hands to start the game and answer the questions on the energy quest! This game is developed by the engineers at Delta Electronics, and allows both one person to experience or two people to collaborate at the same time. For the one-person mode, please choose "solar power" or "thermal power" to start the game. For the two-person mode, one person will carry out the game while the other operates the hand crank generator, which will light up the light bulb on the left side of the screen and increase the battery charge in the image.
