Gravity Train
Like this simulation, if you drill a hole in the earth and throw it in, you can send it to the other side of the earth. This simulation ignores the effects of friction. The earth is assumed to be a … more

Like this simulation, if you drill a hole in the earth and throw it in, you can send it to the other side of the earth. This simulation ignores the effects of friction. The earth is assumed to be a … more
Even if the force works, the speed does not change? When an object moves linearly at a constant velocity, the force applied to the object is zero because there is no change in velocity. If so, is there a motion … more
The diffraction grating is a transparent plate with very narrow lines on the surface. Light (photons) like to go in the same phase. In the same phase, constructive interference occurs. If the phases are different, the waves cancel each other … more
Adjust the wavelength of light to choose the color of light you want. If you adjust the angle of reflection correctly, the phases of the light may coincide. That angle is the angle at which light is reflected by interference. … more
The Lissajous figures The Lissajous figures is a planar shape drawn by the following equation by the parameter t: x = A cos (Bt + C)y = D sin (Et + F) If B:E is an integer ratio, you can … more
Press the ‘C’ button to add carbon, press the ‘H’ button to add a hydrogen atom, and press the ‘O’ button to add an oxygen atom. The added atoms are randomly placed and may not give the correct shape. You … more
* If you are asked to access your location, please allow it. * Your personal data is not stored on the server. * For iOS devices, please allow location access as follows. day and night The earth is spherical, so … more
Polarizers are made of long-chained molecules which absorb light with electric fields. When you shine a light on a polarizer, only a part of the light is passed. The polarizing plate materials absorb only the electric field component of light … more
Constellations and distance to stars If you look at the sky where there is no light on a clear night, there are so many stars that can not count. Thousands of years ago, the ancients linked stars to create constellations … more
Electromagnetic radiation refers to the electromagnetic field waves radiating through space-time, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Types of Electromagnetic Wave Electromagnetic waves are classified based on the length … more
Latitude of Polaris Polaris is far from Earth. Thus, light from the North Star reaches parallel to the Earth. And since the earth is round, the North Star’s latitude varies depending on where it is observed. Incidentally, the North Star … more
Interference patterns seen in thin films If a thin oil film is floating on the water, you will see a beautiful pattern appear on the oil film. This is because the two waves interfere with each other. One wave is … more
