Heisenberg principle-definition, equation, importance & limitation Imagine you were walking along a road casually, and suddenly a double-decker bus crossed you. You can guess its location and speed without much hassle. Meanwhile, you saw a tiny ant is passing nearby. And I am damn sure you stare seriously to find the ant on the floor. Why so? If the same puzzle blinks in a school student's mind, he can convince himself as the bus is large and the ant is small. So, there is a considerable difference in our vision based on their size to locate them properly. Surprisingly, you won't realize the scientific proposal behind it until you understand Heisenberg’s uncertainty principle. What does Heisenberg's principle clarify for us? It is impractical to measure the position and momentum of a nano-sized particle simultaneously without error. It is an uncertainty theory by the German physicist Werner Heisenberg who proposed it in 1927. It is appropriate for only microscopic pa...

 de-Broglie equation-formula, derivation & significance: If everyone is thinking alike, we cannot solve the hurdles of a problem. It seems true if we observe these hypotheses' hierarchy once. Italian physicist Francesco Maria Grimaldi discovered the wave phenomenon of light in 1665. But the uncertainty about light's nature was finally solved by Einstein's explanation of the photoelectric effect. Similarly, Neil Bohr succeeded in describing the structure of an atom with quantized electron orbits. But his stipulation of allowed stationary orbits was only a supposition until the discovery of the de-Broglie equation. Table of contents: 1. What is de-Broglie equation? 2.

Types of electromagnetic radiation The electromagnetic spectrum is a continuum arrangement of electromagnetic radiations in the increasing order of their wavelengths or decreasing order of their frequencies. The Scottish physicist James Clerk Maxwell discovered electromagnetism of light during his watershed treatment in 1864. It disclosed the combined interrelation between the electric and magnetic fields in the propagating light wave. This blog article discusses types of electromagnetic radiation along with the electromagnetic theory of light. Postulates of electromagnetic wave theory: The light was a wave for folks early in the nineteenth century, but the nature of light transmission was unrevealed till 1864. Maxwell proposed electromagnetic wave theory to describe the electric and magnetic field couple characteristics in the disseminating light beam.   It explained the wave nature of light and emphasized the continuous transmission of radiant energy. The key postulates of this ...
