Conduction The ‘conduction’ of heat is how heat is transferred by moving particles that make up an object to neighboring particles. Heat can be transferred even if the particles do not move, mainly by vibration or … more
Convection in the room There are three ways to transfer the heat: conduction, convection, and radiation. Convection is the method by which heat is transferred by the direct movement of particles that make up a liquid … more
The image captured on the camera is divided into three primary colors of light. Notice & Information The following web browsers are currently supported: Windows: Microsoft Edge, Google Chrome Android: Microsoft Edge, Google Chrome iOS: Safari … more
If three primary colors of light (red, green, blue) are illuminated in a dark place, how will it look? Notice & Information The following web browsers are currently supported: Windows: Microsoft Edge, Google Chrome Android: Microsoft … more
Movement on the pulley Two objects are connected by a string on a fixed, frictionless pulley and are moving together. In this case, the mass of the string and pulley is ignored. Since tension \(T\) and … more
Waves in spring When the left end of the spring vibrates, the vibration is transmitted to the other end. A spring can vibrate horizontally or vertically. Fixed-end reflection When a wave reflects off a fixed-end, the … more
What is the main frequency of the sound around us? Please allow the simulation to request microphone access. If you have set up the microphone or refreshed the webpage screen, touch anywhere on the screen once. … more
Charging and discharging of capacitors A capacitor is a component that stores electrical energy in the form of an electric field. Assemble the capacitor and resistor on the breadboard, as shown below. When you press the … more
This simulation shows the surrounding sounds as waveforms. Please turn off the silent mode on your mobile device to allow microphone detection. For PC, please allow permission to use the microphone. No voice data is stored … more
Color and Eye Recognition Visible light has various colors. Light has a different color depending on the wavelength (or frequency). So, how do people perceive color? Cone cells in the eye’s retina recognize color. There are … more
Magnetism of matter Materials can be divided into three types: ferromagnetic, paramagnetic, and diamagnetic, depending on how they react to an external magnetic field. Ferromagnetic In ferromagnetic materials, each atom acts like a magnet. In ferromagnetic … more
What is the difference between a magnet and an electromagnet? Let’s assume there is a small container you can’t see inside. There is a magnetic field around this container that can attract iron. Then, can you … more
