## Alpha Rays (Alpha Particles) | Definition, Uses, Properties

Definition of Alpha Rays Alpha rays is made up of alpha particles. An alpha particle, structurally equivalent to the nucleus of a helium atom, consists of two protons and two neutrons.  Other Definition of Alpha Rays During nuclear decay, the liberated energy (decay energy) is shared between the daughter nucleus and the alpha particle. The … Read more

## Quantum Mechanical Model (Erwin Schrodinger Model)

In 1926, Austrian physicist Erwin Schrödinger (1887–1961) used the wave-particle duality of the electron to develop and solve a complex mathematical equation that accurately described the behaviour of the electron in a hydrogen atom. The quantum mechanical model of the atom comes from the solution to Schrödinger’s equation. Quantization of electron energies is a requirement … Read more

## Rutherford’s Atomic Model (Plum Pudding Model)

Rutherford’s Atomic Model – The plum pudding model is given by J. J. Thomson failed to explain specific experimental results associated with the atomic structure of elements. Ernest Rutherford, a British scientist, conducted an experiment and based on the observations of this experiment, he proposed the atomic structure of elements and gave Rutherford Atomic Model. … Read more

## Atomic Models | Types of Atomic Models, Importance

Atomic Models: After discovering electrons and protons, the scientists started thinking of arranging these particles in an atom. Different models were proposed to explain the distribution of subatomic particles in an atom. There has been a variety of atomic models throughout the history of atomic physics that refers mainly to a period from the beginning … Read more

## Faraday’s Law of Electromagnetic Induction

Definition of Faraday’s Law Faraday’s law of electromagnetic induction, also known as Faraday’s law, is the basic law of electromagnetism which helps us to predict how a magnetic field would interact with an electric circuit to produce an electromotive force (EMF). This phenomenon is known as electromagnetic induction. Michael Faraday proposed the laws of electromagnetic … Read more

## Radioactivity | Definition, Discovery, Types, Applications

Definition of Radioactivity As its name implies, radioactivity is the act of emitting radiation spontaneously. And this is done by an atomic nucleus that. Because for some reason, is unstable; it “wants” to give up some energy to shift to a more stable configuration. During the first half of the twentieth century, much of modern … Read more

## Anode Rays (Canal Rays) | Experiment, Procedure

Definition of Anode Rays The streams of positively charged particles are called anode rays or positive rays, or canal rays. Discovery of Anode Rays Anode rays (or Canal rays) were observed in experiments by a German scientist, Eugen Goldstein, in 1886. Goldstein used a gas discharge tube that had a perforated cathode. A “ray” is … Read more

## Cathode Rays | Definition, Discovery, Experiments

Definition of Cathode Rays Cathode rays are the beam of electrons traveling from the negatively charged Cathode to the positively charged anode at the other end of the vacuum tube. These Cathodes travel in a straight-line path at high speed when a voltage difference is applied to the electrodes. The detection of cathode ray was … Read more

## Cathode Ray Experiment | Apparatus, Working

Cathode Rays Experiment J.J.Thomson conducts three experiments with cathode ray experiment. Experiment-1 In 1897, great physician J.J. Thomson conducted his first cathode ray tube experiment to prove that rays emitted from an electron gun are inseparable from the latent charge. He built his cathode ray tube with a metal cylinder on the other end. The … Read more
