Introduction Brail system is developed for visually impaired people. Generally writing systems are the visual representation that is used to share our feelings and communicate with each other. Many types of communication were followed from the early times. Braille is one such system of communication. In such systems, the conveyer and the reader should be able…

Introduction The act of reflection can be referred to as such kind of phenomenon where the light can be observed to bounce back after being fallen on a particular kind of surface that is considered as the obstacle on the path of the travelling of a ray of light. Based on this concept of physics,…

Introduction Everything around us is visible to our eyes because of light only. Our bodies are completely useless in the absence of light called darkness. Sunlight also acts as a renewable source of energy to generate electricity using solar cells. But, the main question, which was a matter of discussion among various physicists was –…

Introduction The eye is one of the 5 sensory organs apart from the nose, ear, tongue and skin. It enables the power to see every object that is around us. In simple words, it works like a camera that captures visions. Eyes also catch the light rays from our surroundings and make them convert in…

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 A shadow is known to be originally a region of space, where there is no visibility of light because the non-transparent object is obstructing the rays of light. The intensity and position of the light source impact the features of the shadow type that is created. What is Shadow? A shadow is referred to…

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…
