Ohm’s Law is probably one of the most well-known laws in electricity and physics. For students in electronics, Ohm’s law is as important as Einstein’s Relativity equation (E = mc²) …

## Kohlrausch’s Law

Kohlrausch’s law, also known as Kohlrausch’s law of independent ionic migration, was established by the German physicist Friedrich Kohlrausch in 1875-1879. This law is in connection with the molar conductivity …

## Tyndall Effect

When a beam of light passes through a colloidal solution, the path of the beam of light gets illuminated due to the scattering of light by colloidal particles. This is …

## Nuclear Energy: The Benevolent Cousin of the Bomb

Ever since the discovery of the nuclear fission of Uranium by Otto Hahn and Lise Meitner in the late 1930s, it has been associated with weaponry. Unfortunately, due to this …

## Five States Of Matter Explained

Firstly, let us know about matter. Matter is basically defined as any substance that has mass and takes up space by having volume. We all know that matter is made …

## Fourier Series

Introduction Fourier series is a mathematical function that is formed by the sum of scaled sine and cosine functions, over an interval. With adjustment of the scales of the sine …

## The Gas Laws

The gas laws are a set of laws and equations that describe the behavior of gasses. It was developed by multiple people over two centuries.  They were developed to provide …

## Rutherford’s Atomic Model

Soon after the discovery of fundamental particles, a lot of scientists tried to explain the distribution of these particles inside the atom with an atomic model. One of such models …

## Bohr’s Atomic Model

Bohr’s Atomic Model was introduced by Niels Bohr in 1915. It was basically a modified version of Rutherford’s Atomic Model wherein Bohr explained that electrons move in fixed orbitals (shells) …

## Lenz’s Law

Lenz’s Law is a law in electromagnetism, which states that an induced electric current flows in a direction such that the current opposes the change that induced it.  This law …

## Lens Maker’s Formula

Lens Maker’s formula is a formula that relates focal length, radii of curvature, and refractive index of the lens. As different devices need lenses of different focal lengths, this formula …

## Laws of Thermodynamics

Everything in this universe exists in two fundamental forms: energy or matter. Thermodynamics deals with a particular form of energy, which is heat energy. Derived from Greek it means ‘movement …
