This simulation analyzes the sound around you and displays it as a spectrum. The simulation works by recognizing the surrounding sounds. In the case of PC, please grant permission to use the microphone. Voice data is not stored on servers, … more
A solid metal can be made by grouping several hot gaseous (monatomic) metals together. What is the difference between emission spectra in the gas (monatomic) and solid state? The simulation above is a simple example and is not representative of … more

Doppler Effect We have heard an ambulance siren and felt that the ambulance is getting closer. When the ambulance approaches, the sirens sound higher, and when they move away, the sirens sound lower. That is, when an ambulance approaches with … more
Surface temperature and color of object When the iron is heated, it is initially dark red, but as the iron’s temperature rises, it gradually takes on a yellowish color. This is because the light emitted by the iron changes as … more
Spectrum of hydrogen At the time of Rutherford’s experiments, chemists analyzed chemical components using spectroscopy, and physicists tried to find what kind of order in complex spectral lines. For example, a hydrogen arc tube containing hydrogen, a light element, shows … more
