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…

Introduction In accordance with the laws of physics, for the production of an image, the rays of light, need to come from an object and meet at a particular point after being reflected and refracted. At the point where the rays meet, the image is formed. In the simple dictionary, anything that emits light rays…

Introduction In our day-to-day life we observe various phenomena like after the rain a rainbow is formed in the sky, splitting of white light into seven colors, and when water falls on petrol it also shows different colors. These all phenomena are related to the optical phenomenon of light. In this tutorial, we will discuss…

Introduction Brewster’s law is studied in optics. the science of light. If light waves could pass through all materials perfectly, you wouldn’t be able to see anything. All materials would turn invisible. On the other hand, if materials reflected all light perfectly, they would always appear white instead of coloured. Colours are visible only because materials…

Introduction There are five states of matter and gas is one of them. Empty spaces are filled by gases. The atmosphere is full of gas molecules. It contains different gas molecules. The oxygen gas molecule which is necessary for breathing is also in our atmosphere along with many other gas molecules. Every matter in the…

Introduction This gaseous theory describes the behavior of the gases contained in some vessels. The particles which are molecules or gases are always in random motion as they continuously move and collide with each other and collide with the container also. Also, there is some pressure and temperature within the container. The path acquired by…

Introduction In our daily life, we commonly observe the motion of the air molecules when a light ray enters the dark through a small hole. the motion of air molecules is studied by the kinetic theory. With the help of the kinetic theory of various properties of the gas can be defined in terms of…
