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 refractive index is proportional in nature to the critical angle. In a situation, when a light ray is traveling from a single medium to another medium, a critical angle is found to be created. This type of angle strikes the main boundary that is situated between the lower index and the medium. At that time, the ray does not reflect in the first medium of traveling. The limit of the critical angle can be measured by implementing a particular formula. Features of Critical angle This angle is highly affected by the changes within a refractive index. The refractive ... Read More

Introduction The present tutorial will focus on the explanation of the definition of refraction which states a redirection of a wave or the ray of light while passing from one objective medium form another. Based on the concept of physics, the tutorial will include an explanation related to the reason, for which the refraction of light is happen. Moreover, the tutorial will include a discussion regarding the laws of refraction and the effects of refraction along with the applications as well. What is refraction? Figure 1: Refraction It is known to all that light travels at the highest speed ... Read More

Introduction A ray of white light while travelling obliquely from one medium to another, it is seen to deviate from its original course. Along with that, while passing through a transparent substance like a glass prism, the white light distributes in its constituent spectrum of colours. Based on these two concepts of physics, the tutorial intends to include an effective discussion regarding refraction and dispersion of light through a prism. What Is The Dispersion of Light? The phenomenon of dispersion can be defined as the splitting of visible light into its component colours. Light is considered a mixture of different ... Read More

Introduction Light is known as the form of energy which can reflect sometimes, based on the objects it falls on. In some cases, objects like mirrors or any type of metal that is polished can reflect the light. Moreover, it also occurs only when the rays of light reflect on a surface and reverses the direction. Electromagnetic radiations are an example of light reflection that occurs when the waves encounter a boundary of the surface which does not absorb the energy and results in a reflection of the waves of light. Figure 1: Reflection of light Reflection of Light The ... Read More

Introduction In the time when rays come from a source and bounced back, the process is named reflection. The concept of reflection of light was first introduced by Euclid, an ancient Greek Mathematician. At certain times, rays of light often approach a smooth and clear surface and reflect at the same angle. What is the Reflection of light? The reflection mode of light depends on the nature of the surface. After hitting the surface, the rays bounce back in the exact same direction if the surface is polished and smooth (Kittiravechote & Thinarat, 2021). In the case of a rough ... Read More
