What is a Water Ionizer
A water ionizer is an electronic home appliance which ionizes water and makes it alkaline by raising its pH level. It also lowers the ORP (Oxidation Reduction Potential) of water. ORP is the tendency of water to oxidize or reduce other substances. Continue reading “Water Ionizer”
Cathode Ray Tube Definition
A cathode ray tube or CRT is a device that produces cathode rays in a vacuum tube and accelerates them through a magnetic and electric field to strike on a fluorescent screen to form images. Continue reading “Cathode Ray Tube (CRT)”
What is the Casimir Effect
The force of attraction between two closely placed parallel uncharged conducting plates in a vacuum is known as the Casimir effect. Continue reading “Casimir Effect”
The Ruben’s tube is a classic physics apparatus to show that sound waves are primarily pressure waves. It can be considered to be an older version of the oscilloscope and gives a visual demonstration of standing waves with the help of flames. Continue reading “Ruben’s Tube”
What is Ionizing Radiation?
Ionizing radiation is a kind of radiation which has enough energy in it to knock out electrons from atoms or molecules and make them charged or ionized.
In today’s age, people living in tall buildings seldom worry about how ground water is lifted to their apartments. However, in ancient times, lifting up water to great heights was a matter of concern. A device known as Archimedes’ Screw came to aid in this hour of need. Its invention is attributed to the famous Greek scientist and mathematician Archimedes of Syracuse in the 3rd century B.C., on his visit to Egypt. It finds applications even today.
