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

To understand refraction and reflection of a plane wave on a plane surface using wavefront, there are some concepts that you need to be clear with. Refraction of a wave Waves change direction when they pass from one medium to another. This phenomenon is called refraction.  Refraction can occur in different types of mediums like

Lenses are transparent mediums bounded by two surfaces; of which, at least one must be curved. When the gap between two surfaces of a lens is very small, it is considered thin. When the focal length is positive, a lens will be converging; if it is negative, it will be diverging. As a consequence, we

Lens Formula Lens formula is given as:      1/a-1/b=1/f  Where, a = distance of the image from the lens b = distance of the object from the lens f = focal length of the lens This lens formula is applicable for both concave and convex lenses. Introduction A lens is a piece of transparent

The visible light spectrum, like all other types of light, is absorbed and released in the form of tiny packets of energy known as photons, which are tiny packets of energy. These photons exhibit both the characteristics of a wave and the characteristics of a particle. As a result, this type of phenomenon is referred
