Doppler effect Electromagnetic waves (or sound waves) come into contact with another object while traveling; part of the wave is absorbed or reflected. A moving ball likewise absorbs or reflects some of the incoming waves. If … more
* After setting the small object’s mass, position, initial velocity, and initial direction of movement, turn on the ‘Run’ checkbox to start the simulation. * The gravitational constant of the celestial body were assumed to be … more
CRT TV CRT TV is an image-receiving device that uses cathode rays. It was widely used as a TV receiver until the mid-2000s. However, it had the disadvantage of being large and heavy. Afterward, it gradually … more
x y Vx Vy * The mass and gravitational constant of the celestial body were each assumed to be ‘1’. * You can edit the position and speed of each celestial body while not running. * … more
Why does a slightly curved path take less time than a straight path? Ants can move faster on flat stones than on rugged grass. Therefore, travel time is the shortest on slightly curved paths. This principle … more
Light has both particle and waves properties at the same time. Likewise, de Broglie (France, 1892 – 1987) thought that such things as electrons that had so far been considered particles might possess wave nature (1932). … more
You can drag the path of light. 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 … more
Reset Wave In science, a wave is a phenomenon in which energy is transmitted through a medium. It is the only energy that is transmitted through the wave. The medium only vibrates but does not actually … more
You can set the movement of the magnet as you wish. Observe the electromotive force generated depending on the position and speed of the magnet. Electromagnetic induction Moving the magnet around the inductor will change the … 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 … more
A cathode ray tube (CRT) is a device that produces cathode rays (a stream of electrons). The inside of the tube is evacuated or filled with a noble gas. When a high voltage is applied to … more
Let’s assume there is a light source in the middle of the train and sensors on both sides to detect the light. From the point of view of an observer inside the train, the two light … more
