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
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
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
Rainbow by Raindrops
A rainbow is a natural phenomenon where the dispersion of light is most visible. As you know, We can see a rainbow after rain because the water droplets bend and disperse the light. For example, if … more
Seismic Wave
Investigation inside the Earth The surest way to see what the Earth is like is to penetrate and see it yourself. However, there is a limit to penetration because the temperature and pressure rise as you … more
Refraction on water
Refraction is the bending of a wave caused by a change in its speed as it moves from one medium to another. This occurs because of the slow speed of light in dense materials. Examples of … more
Phase array
Spinning radar In general, electromagnetic waves (radio waves) propagate in all directions. In this case, radio waves can be transmitted or received in any direction. However, as the distance increases, the strength of the radio wave … more
Cochlear and Audible Frequency
The sensing part is slightly different depending on the frequency of sound. Move the slide bar to check. Cochlear Inside our ears, there is a sensory organ that senses sound. The overall shape resembles a snail … more
