Introduction Angle of incidence and its measurement is a key concept of Optics. Light rays when incident on the surface like walls and mirrors, will reflect and get dispersed in the environment. The science of optics studies the traversing of light and its changing characteristics when passing from one medium to another medium. The terms like…

Introduction: Coherent Sources of Light Light sources which produce light waves with the same frequency, constant or zero phases difference, and same wavelength are called coherent sources of light. Two coherent light waves make a sustained interference pattern. Both coherent waves make fixed maxima and minima overtime when they overlap with each other. Images Coming…

Introduction Bragg’s law is an important concept of atomic and molecular physics. You are already aware that atoms are the building blocks of this universe. They are the foundation of every bit of matter in this universe. But that is not all that we know about the microscopic world. Indeed, we have even managed to divide…

Introduction Light has the characteristics to be reflected, transmitted or absorbed when it falls on a surface with a certain angle of incidence. Light appears as the only electromagnetic radiation that is capable of reflection, transmission and absorption while being visible to the human eye. The process of absorption, transmission and reflection are influenced by…

Introduction The light transmission of any object completely depends on the basic material of the objects. If the object allows a hundred per cent light transmission it is called transparent, and if the light transmission capacity of the object is less than a hundred per cent then it is a translucent object. On the other…

Introduction From the year, 1666 to 1672, Newton conducted several experiments with the prism and sunlight to recognise the true colour of sunlight. However, he was quite successful in determining the colour of the sun to be white which is seen as a combination of the seven respective colours we experience in a rainbow. With…

Introduction The phenomenon of pressing waves around obstacles is commonly known by the term diffraction, based on this simple concept of physics, the present tutorial will explain the definition of a single-slit diffraction while explaining the pattern of diffraction. Furthermore, the tutorial will include an explanation of the formula of single-slit diffraction along with defining…

Introduction Raman scattering is an ideal technique that creates dispersed photons with distinct frequencies based on the rotational and vibration properties of the scattered molecules. Raman scattering is utilised to acknowledge the materials by physicists and chemists. In recent times, lasers are utilised to record the spectra whereas photographic plates and mercury lamps were utilised…

Introduction Albert Einstein discovered the particle nature of light based on the fact, that metals eject electrons when it comes in contact with light. Electromagnetic effects are integrally associated with this nature of light. According to Albert Einstein, electromagnetic energy is associated with significant packets of quanta, which are also known as photons. As per…
