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
Camera In optics, an image is recreated by collecting some of the light emitted by an object. Devices that recognize images include eyes and cameras. The light entering the camera passes through the aperture and lens, … 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
