de Broglie hypothesis for matter waves in quantum theory

Hypothesis is a predicted theory that satisfies other phenomena but isn’t verified experimentally. Scientist de Broglie gave a such type of theory for the matter particles which plays important roles in Quantum mechanics. In this article, we are going to discuss de Broglie hypothesis for matter waves in quantum mechanics, its explanation and formula and … Read more

Explanation of Photoelectric effect by Einstein equation

Albert Einstein won the Nobel Prize in 1905 for his explanation of Photoelectric effect. There were some failures of classical mechanics to explain this phenomenon. Then Einstein explained it on the basis of quantum theory. In this article, we are going to explore the definition and properties of Photoelectric effect explained by Einstein and will … Read more

Difference between nuclear fission and nuclear fusion in tabular form

Nuclear fission and nuclear fusion are two nuclear phenomena to produce nuclear heat energy. But these two phenomena occur in different conditions and the amount of heat generation is also different in these two phenomena. In this article, we are going to discuss the definition, properties, examples, uses and differences between nuclear fission and nuclear … Read more

Bohr atomic model of Hydrogen | Bohr theory

At first, scientist Rutherford gave the atomic theory of atoms after the alpha particle scattering experiment. But this theory was unable to consistent with the stability of an atom. This theory of Rutherford was based on classical mechanics. To explain the stability of atoms, scientist Niels Bohr gave a theory or model which is known … Read more

Radioactive isotopes of elements – radioisotopes

In another article, we have learned that the elements that emit alpha, beta and gamma rays spontaneously are called radioactive elements. All elements are not radioactive elements. Again, all isotopes of an element are not radioactive. In this article, we are going to discuss which isotopes of radioactive elements have radioactivity property. Here, we will … Read more

XOR gate circuit diagram using only NAND or NOR gate

XOR gate or Exclusive OR gate is a widely used logic gate in digital electronics. It is one of the logic gates in the Computer which is available in IC form. We discussed basic logic gates like OR gate, AND gate and NOT gate earlier in another article. XOR gate can be constructed using only … Read more

Basic logic gates with truth tables and diagrams

Logic gates are the basic building blocks of digital electronics that follow different logical operations. These gates have significant roles in the construction of logical circuits for different computations. Digital electronic devices contain integrated circuits (ICs) which are made of logical gates. In this article, we’re going to explore basic logic gates with truth tables, … Read more
