Introduction Light travels a straight path when it bends while travelling in a single direction. A certain change in the speed of light causes a directional change in its path and that is when refraction happens after light passes a boundary from one transparent medium to another. The bending of light by refraction makes it possible for the human retina to observe prisms and rainbows. Without refraction of light, the human eye cannot focus on the pathway of light. What is Refraction of Light Refraction refers to the process of bending light immediately after it passes from one transparent substance ... Read More

Introduction The direction of light immediately changes after it passes from one medium to another. In simple words, light bends while travelling from one medium to another. In the case of a glass prism, the degree of refraction varies with the light's wavelength. It eventually gets segregated into seven different lights while passing through a glass prism in real-time. When the wave of the light travels from one optical medium to another, refraction takes happens. It is mostly caused by the difference in optical density between different mediums. What is the Refraction of Light in a glass prism? In a ... Read More

Introduction The present tutorial will explain the reflection and the laws of reflection that helps to create a mirror image after the ray of light bounces on the surface of a flat mirror. The tutorial will further explain the classification of lights along with the laws including Huygens Principle and Law of Refraction. Along with that, the tutorial will include how the angle of reflection changes for a rotational in comparison to a fixed mirror. What Is The Reflection of Light? Reflection can be defined as the result of a change in direction of the angle of light or the ... Read More

Introduction The reflected ray of light is every time expressed to be similar to falling on a normal surface. The comprehension process of images that is relying on a plan and curved mirror are identical to applying the law of reflection. Unlike the mirrors, most surfaces that are natural on the wavelength scale of light can help in creating parallel light ray's incidents. In this tutorial, the reflection law of light is discussed with the use and different types of light reflective laws. The Law of Reflection The reflection of light is an integrated part of physics while studying the ... Read More

Introduction The word 'Lateral inversion is a significant term, associated with the reflection theory in physics. The reversal of a mirror's image possesses an integral connection to the reflection of light. In comparison to the object's real appearance, the image in the mirror is presented in the exact opposite direction. This state of the image is presented as the lateral intervention of a reflection. The other meaning of lateral is sideways. As a surface of a place mirror, the points of an image are situated very far placed from the real images. The changes in a wave form's direction are ...

Introduction A Rainbow is the outcome of reflection and refraction of light which includes a transformation in direction of waves. Rainbows are caused by different conditions of the atmosphere and the phenomenon of sunlight. Apart from the physical concepts, the rainbow is demonstrated as the symbol of hope in distinct cultures. In many cultures, people often consider the rainbow as an inspiration, good fortune and promise. Rainbow represents a personal meaning in everyone's life which represents inclusion and diversity and the facts of embracing friendship and love. A Rainbow is not considered a matter state and it happens by reflection ... Read More

Introduction In the field of optics, photometry is defined as the term that provides the measurement of light, as recognized by the eye of a human being. This measurement deals with measurements associated with psychophysical attributes' of the energy of electromagnets that come under the visibility ranges of human eyes. However, the concept of photometry is quite different from radiology as radiology deals with the measurements associated with radiations from the optics. In dealing with this concept of photometry, the term luminous holds much significance. Definition of photometry In simpler terms, photometry can be stated as the measure ... Read More

Introduction The moment of inertia (MOI) of a body is determined by parallel axis theorem that is parallel to mass of object’s axial line and it also passes through the centre of gravitational force. The PAT suggests that the summation of moment of inertia of a body and product of the mass of a body and square of the axis distances defines the PAT. It helps in finding MOI of objects like rod, discs and a lot more. In this tutorial, the parallel axis theorem will be discussed further. History of Parallel Axis theorem The ... Read More

Introduction We know that in the gravitational field an object creates gravitation around it and if any other object is placed inside that region, it will experience a gravitational force. The gravitational field is created due to the masses present but the electric field is created due to charges and the time-varying magnetic fields. Electric Field We define the electric field as the region or space around a charge within which if we place another charge, then it will experience an electric force on it which can be attractive or repulsive depending on the polarity of the source and the ...

Introduction A system of two charges +q and -q, equal in magnitude and opposite in polarity segregated by a small distance '2a' is called an electric dipole. The electric dipole moment vector of this system is given as: Images Coming soon Where '2a' is the vector that joins the negative charge to the positive charge. Electric Dipole The SI unit of electric dipole moment is coulomb-meter(Cm). The electric dipole moment gives the measure of strength linked with the electric dipole. The middle point of the line joining the two charges +q and –q is called the centre of the dipole. ... Read More
