Introduction: Newton disc was invented by the great scientist Isaac Newton. This experiment basically consists of 7 colors in a single disc. These colors are rainbow colors. When the disc is rotated, the colors fade into a white color. Thus, in simple terms, Newton mentioned that the white light is a combination of the seven … Read more
Introduction: Herons fountain model is named after the physicist and mathematician Heron of Alexandria. It is a hydraulic machine is a steam engine that emphasizes on the study of pressure of air and steam. There are many variations of this model that are studied today which explains the theory of hydraulics and pneumatics. Herons fountain … Read more
Introduction: Air pressure, also known as atmospheric pressure is the weight of the molecules pressing on the surface of the earth. It is measured in barometric units. Barometers have a chemical called mercury within them. This chemical helps to read the atmospheric pressure in a room, or in an enclosed place. It is also the … Read more
