  • Types of Natural Radioactivity

    What is Natural-radioactivity? All the elements beyond hydrogen and helium were made in nuclear reactions in the interiors of stars or in explosive supernovas. Both radioactive and stable nuclides are created in these processes. The solar system is composed of…

  • How does a Diffraction grating work?

    “The diffraction grating is a useful device for analyzing light sources. It consists of a large number of equally spaced parallel slits.” Its working principle is based on the phenomenon of diffraction. The space between lines acts as slits and…

  • Bipolar junction transistor(BJT):Applications & characteristics

    What is transistor? A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. Or A transistor is a device that regulates current or voltage flow and acts as a switch or gate for electronic…

  • Types of radioisotopes and their examples

    Radioisotopes are formed by Isotopes, which are atoms with the same atomic number and different mass numbers. Some Types of radioisotopes are Radioactive sodium carbon, phosphorous, Iodine, Gold. Radioisotopes examples Examples of natural radioisotopes are 238 U (uranium), 40 K (potassium), 232 Th (thorium) and their child nuclei (obtained by…

  • Properties of alpha, Beta and Gamma rays with uses and differences

    Three types of radiations are emitted from radioactive elements that are Alpha, Beta, and Gamma radiations. This post also includes Properties of Alpha, Beta, and Gamma rays. This post includes: Radioactivity Definition Natural radioactivity Definition Nature of Radiations Properties of…

  • Uses and applications of total internal reflection

    When the angle of incidence becomes larger than the critical angle, no refraction occurs. The entire light is reflected into the denser medium. This is known as a total internal reflection of light. Prisms, binoculars, and optical fibers are a…

  • Thermal radiation:Definition,examples and properties

    Thermal radiation Radiation emitted by such a body due to its temperature is called thermal radiation. All bodies not only emit such radiation but also absorb it from their surroundings. If the rate of absorption and emission from a body…

  • Uses of laser in Everyday Life

    List of uses of laser and applications in the field of medicine, industry, and agriculture The intense heat produced in a small area by a laser beam is also used for welding and matching metals and for drilling tiny holes…

  • What is Photovoltaic effect?

    Photovoltaic effect An effect arising when a junction exists between two dissimilar materials and one of the materials is exposed to electromagnetic radiation, usually in the range near-ultraviolet to infrared. The two materials may, for example, be a metal and…
