Correction of Near-sightedness & Far-sightedness
Focusing The light started from the object must have arrived exactly at one point on the retina to see things in detail. On the other hand, if the light from one point of the object is … more
Equilibrium Constants
2●\(\rightleftharpoons\)● Chemical equilibrium In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations that have no further tendency to change with time. In an equilibrium state at … more
Tuning Fork and Sound Wave
Tuning fork The tuning fork has a structure that combines the ends of two sticks. When the tuning fork is vibrated, the tuning fork repeatedly approaches and then moves away from each other. The vibration mechanism … more
Double-Slit Experiment
Double Slit Experiment The double-slit experiment is the observation of the pattern that a single wavelength of light creates after passing through two slits. Light passes through each slit and then creates a light or dark … more
Polygonal Wheel
Polygon Wheel Should the wheels always be round? All polygon wheels can roll smoothly. To do this, you need a suitable floor. How is the floor for the polygonal wheel to roll smoothly? The floor shown … more
CMYK Color Division by File Drop
When you upload an image file, the simulation divides the image into four primary colors (Cyan, Magenta, Yellow, Black) of the pigment. You can see the original colors by printing on transparent transparencies and then overlaying … more
CMY Color Division by File Drop
When you upload an image file, the simulation divides the image into three primary colors (Cyan, Magenta, Yellow) of the pigment. You can see the original colors by printing on transparent transparencies and then overlaying them. … more
Particle Simulation of Thermal Conduction
About this simulation This simulation shows the particle’s temperature by its color.● Red means high temperature.● Blue means low temperature. We apply Hooke’s law between particles.(\(f=-kx\)) Thermal Conduction Conduction is a method of transfer of heat … more
Conduction
Conduction of Heat If a high-temperature object and a low-temperature object are attached to each other, the high-temperature object’s heat moves to the low heat by molecular motion. Examples of Conduction that can be seen around … more
Microphone and Speaker
The simulation works by recognizing the surrounding sounds. Please turn off the silent mode on your mobile device for microphone detection. In the case of PC, please grant permission to use the microphone. Voice data is … more
Three Primary Colors
* Touch the screen to move the colored circles. Three primary colors of light Red, green, and blue are called the three primary colors of light. You can create any color by adjusting the light of … more
