Science Simulations
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
Photoelectric Effect The photoelectric effect is the phenomenon that the electrons pop out when a light beam incident on a metal surface. It can be thought that the energy of light is transformed into the form of electrical energy. However, … 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
The energy level of the atom Atoms are made up of an atomic nucleus and electrons that revolve around the nucleus. In Bohr’s atomic model, electrons can change their position by receiving energy (mainly light energy). But what’s unique is … more
* This simulation take the spectral data from NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY. When heat is applied to the atoms, some electrons can have high energy levels and fall to the lower levels. Some electrons emit as much energy … more
This simulation assumed that a candle emits all its energy in only one specific wavelength. The power of the candle is assumed to be 50W. The emitted wave diagram is for understanding only and does not represent the actual wavelength … more
Why we can’t see atoms under an optical microscope? The process by which we see objects is based on light. Therefore, the resolution of object recognition depends on the light. Just as a tool must be precise to open a … more
