Yes, a Nuclear reaction known as Nuclear Fusion reaction takes place in the Sun. The sun provides both heat and light energy. These two energy arises due to the Nuclear fusion reaction that happens inside the core of the Sun. This specific type of reaction that occurs insides the sun is called Proton-Proton Fusion Reaction. … Read more

Units of Radioactivity There are four common units of measurement in Radioactivity in nuclear Physics. They are Curie, Rutherford, Becquerel, and Roentgen. Curie It is defined as the quantity of a radioactive substance that undergoes 3.7 x 10 10 disintegrations per second. Referred from 1 gm of radium 226. Rutherford (RD) It is defined as … Read more

Radioactive Displacement Law Soddy and Fajan proposed displacement laws concerning the daughter nucleus produced during an alpha and beta decay. We state them below: It emits the alpha particle when the daughter nucleus is formed. The atomic number is less by 2 units and the mass number is less by 4 units than the parent … Read more

Alpha, Beta and Gamma Rays Alpha, Beta, and Gamma Rays are emitted when a radioactive nucleus undergoes disintegration naturally or induced. Properties of Alpha (α) It is the Helium Nucleus 2 He 4  that has two protons and two neutrons. It is a positively charged particle, the charge of each particle is +2e. The Ionising … Read more

Conduction The molecules in the solids are tightly packed. When heated at one end, the molecule absorbs heat and it vibrates in its position, and the molecule at the other gets heated. These heated molecules, in turn, heat other molecules, till everything gets heated. “The process of heat transfer in solids from an area of … Read more

Mercury and Alcohol are used in the thermometer because they remain in liquid form with temperature change. The best conductor of heat among liquids is mercury and also it does not stick to any surface, so it is widely used in thermometers Even a small change in temperature changes the volume of the Alcohol or … Read more

Input Transducer A transducer is a device that converts the change in a physical quantity such as pressure, temperature, sound to an electrical signal or vice versa. The transducer converts the information which is in the form of sound, music, pictures or computer data to electrical signals. The microphone is an example of a transducer … Read more

Nuclear power plants in India India’s Nuclear programme had its origin in March 1944, which was started by Homi Jehangir Bhabha who founded the Nuclear research centre, at the Tata Institute of Fundamental Research. As of October 2021, there are 7 nuclear power plants in India and 23 nuclear reactors are operational. Its total installed … Read more

What are two types of Nuclear Reaction? Basically, there are two types of reactions in nuclear energy production they are Fission and Fusion reactions. Nuclear fission German scientists, Otto Hahn, and F.Strassman in 1939 discovered that when Uranium Nucleus is bombarded with a neutron, it splits into two smaller Nuclei among with emission of neutrons … Read more
