Reflection, refraction

When light flows through a transparent medium and bends, this is known as refraction. The optically rarer medium is one in which the velocity of light is higher, whereas the optically denser medium is one in which the velocity of light is lower. The refraction phenomenon is caused by differing light velocities in different media. […]

Everything that we can see in the world is processed by our minds as images. Real images and virtual images are the two forms of images. A virtual picture is one that is made by the divergence of light beams, whereas a real image is one that is formed by the convergence of light rays.

Raman Scattering, commonly referred as the Raman Effect, is a phenomena in which photons are scattered inelastically by matter, with the scattered photon’s frequency differing from that of the input photon. It implies that as the photon reaches the surface of the matter, the energy level and direction of the light will change. The effect occurs

Introduction  Reflection: The change in direction of a wavefront at an interface between two distinct media such that the wavefront returns to the medium from which it originated is known as reflection. The law of reflection says that for specular reflection the angle of incidence is equal to the angle of reflection. Mirrors are the

Introduction Before learning about the power of the lens, we have to understand the term lens. Lens is a piece of glass or transparent material which is usually circular and has two surfaces that are polished in a specific manner for converging and dispersing of light rays. The greater the power of the lens, the

Introduction The power of the lens is one of the most exciting topics in ray optics. A detailed explanation of this topic is given in the below article. This article will be helpful for the learners as they can learn more effectively and efficiently. Firstly, before knowing about the power of the lens, we have

When a ray of light strikes a surface, it can have one of three effects: reflection, refraction, or absorption. When it hits a regular surface, the majority of the light is absorbed. As a result, mirrors are polished surfaces covered with mercury that reflect the majority of the light that falls on them. We may

Introduction Physics index is also known as the refractive index in physics. The term “refractive index” refers to a numerical value used in optical science. Furthermore, it is devoid of a unit. The ability of a material to refract light is measured by its Refractive Index. To fully comprehend the idea of refractive index, one

A mirror is a piece of equipment that reflects images. When focused through the lens of the eye or the lens of a camera, light that bounces off a mirror will produce an image of whatever is in front of the mirror. Mirrors change the direction of the picture by reflecting it at an angle

Introduction   A mirror formula is a way to predict the relationship between three important points of the mirror – that is – the distance of the object, the distance of image, and the focal length of the mirror. The distance of the object placed is represented by “u”, the distance of the image formed is
