Difference Between Diffraction and Interference
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…

Brewster’s Law: Definition, Equation, Examples
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…

Braille: Helping the Blinds and Visually Impaired
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…

Specular Diffuse Reflection
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,…

Unit of Light
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 –…

The Human Eye
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…

Structure Human Eye Functioning
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…

Angle of Incidence – Definition, Formula, Diagram
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…

Difference Between Reflection and Refraction
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…

Transmission, Absorption and Reflection of Light
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…
