Introduction The human eye has been made of different intricate parts that work together to make a person, able for seeing or having vision. The visual activity of an eye is generally defined by the clarity of the image that has been seen by the human eye. Focussing on such concepts, this present tutorial will…

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 In our day-to-day lives, we experience several phenomena of lights and make use of such phenomena to conduct various works. The phenomenon of reflection basically occurs, in mirrors’ ‘ whereas, refraction normally is seen to occur in lenses. However, it is to be noted that, although both reflection and refraction are the properties of…

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 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…
