  • What is difference between electromagnetic waves and matter waves?

    Difference between electromagnetic waves and matter waves in tabular form Electromagnetic waves     Matter waves These waves have electric and magnetic fields associated with them. Matter waves have no electric and magnetic fields associated with them. These waves can…

  • Difference between SSD and HDD

    The Difference between SSD and HDD is given here. The solid hard disk or in its acronym SSD is a portable storage system that has been marketed to achieve a better public experience with the information that it seeks to…

  • Zener Diode: Symbol, Characteristics and Applications

    what is Zener Diode? A major application for Zener diodes is as a type of voltage regulator for providing stable reference voltages for use in power supplies, voltmeters, and other instruments. In this section, you will see how the Zener…

  • Wheatstone bridge formula Class 12

    The Wheatstone bridge circuit is widely used to precisely measure resistance. Also, the bridge is used in conjunction with transducers to measure physical quantities such as strain, temperature, and pressure. Transducers are devices that sense a change in a physical parameter…

  • Reflection of Light Examples in daily life

    What is reflection of light? When light from one medium falls on the surface of another medium, it bounces back in the same medium such that the angle of incidence is equal to the angle of reflection. There are two…

  • Difference between Analog and digital signal

    There is a key difference between analog and digital signals. An analog signal is a signal generated by an electromagnetic phenomenon that can be represented by a continuous mathematical function with amplitude and period as a function of time, while…

  • Interference of Light Examples

    Interference of light is defined as: “When two or more light waves having the same frequency, same wavelength and same amplitude meet together in a medium at a point, they cancel or enhance the effect of each other at that…

  • list of elementary particles

    How many types of elementary particles are there? The elementary particles are simple particles that are not the combination of other particles. For example, an electron is an elementary particle. There are 30 elementary particles out of which the following…

  • Types of capacitors with applications

    “A capacitor is a device that can store charge.”Apart from resistors and inductors, it is the other basic component commonly used in electronic circuits. It is a device that has the ability to store charge which neither a resistor nor…

  • What is difference between excitation and ionization potentials?

    Excitation potential The potential required to lift an electron from the ground state to some higher state is called excitation potential. Or If the energy supplied to an electron is such that the electron is lifted from its ground state…
