Speaking Sub-atomically In the early definitions of matter, everything made of molecules was included. It was later expanded to incorporate everything that contains subatomic particles. Currently, ordinary matter is considered to be anything made…

As we have discussed during our Physics tuition classes, diodes are mostly made from semiconductors like, germanium and silicon. Diodes allow one direction flow of electric current, however, how do so can vary from…

Generally, quantities are classified as scalar or vector. Scalar quantities are those quantities which have only magnitude while vector quantities are those which have both direction of motion and magnitude. Each and every scalar…

Sound is a movement of rarefaction and pressure waves that can travel for prolonged distances. It’s produced by the particles’ vibration in a given medium; a medium can be defined as the material through…

The word ‘Spectrum’ typically refers to the electromagnetic spectrum which consists of all the electromagnetic radiation frequencies. Previously, the term was limited to light only, but afterwards, it was revised to incorporate other waves,…

James Chadwick was an English physicist, well known for his discovering neutrons in the year 1932. He acquired a Nobel Prize in the physics discipline in the year 1935 for this substantial discovery. Throughout…

A plasma ball, which can also be referred to as plasma globe/dome/sphere/orb/tube, is an ornamental glass ball filled with inert gasses in a half vacuum that has a high-powered electrode at its center. This…

Lenticular lens is a strategy that has evolved immeasurably with time, and it’s even being used today. Generally, it’s a collection of magnifying lenses, which are arranged in a way that one can see…

When temperatures are lowered steadily, below water’s freezing point, (0 ºC), nitrogen, which is the major element of air, becomes liquid. Lowering the temperature further, at about -269 ºC, helium, which is the most…
