Lenses and mirrors

In this article, we will discuss the concept of a plane mirror. The mirror is a reflecting surface. The plane mirror is nothing but a mirror that has a highly polished plane surface. It holds the law of reflection. The plane mirrors are used in many applications in science and technology. This article can discuss […]

Concave mirrors are converging mirrors as they converge the light rays to one point. They are used in different fields like medicine, physics and even chemistry. Before we start exploring the uses of concave mirrors, let us get introduced to how we can determine whether a given mirror is a concave mirror, a plane mirror

Spherical mirrors are a piece of hollow glass sphere being cut by a plane. One surface of the spherical mirror is polished and the other is reflecting. Spherical Mirrors are of two type: Concave mirrors and convex mirrors. The mirror in which the outer bulge surface is polished and the reflection of light takes place

Lenses are curved, transparent objects that refract light. Convex lenses (bulging outward, converging light rays) and Concave lenses (bulging inward, diverging light rays) are two types of lenses. Cameras, binoculars, and telescopes all employ lenses. You must be familiar with magnifying glasses. A single convex lens with a frame makes up a simple magnifying glass.

Introduction Lenses came into use in the late 1500s in the making of magnifying glasses for microscopes or telescopes. For this purpose, it was important to know the focal length of the lenses to combine their powers. Before starting with the main topic, here are a few terms that must be understood first. Concave lens:

A mirror is a reflective surface that reflects light and creates either a real or a virtual picture. When an object is placed in front of a mirror, the object’s image is reflected in the mirror.  The object emits the incident rays, and the reflected rays generate the image. Plane Mirrors Spherical Mirrors A plane

Convex Lens A typical optical lens is made up of two spherical surfaces. We call a lens a biconvex lens or simply a convex lens if those surfaces are curved outwards. The centre of these lenses is thicker, while the corners are thinner. Furthermore, this type of lens can converge and concentrate a beam of

We come across plenty of spherical surfaces unknowingly in our daily lives, but we hardly realise how they work. For example, the spectacles you are wearing and the vehicle mirror you have come with a spherical surface. A change in the light direction or just a bending in the light wave moving from transparent mediums

A microscope is a piece of equipment that magnifies small objects. Some microscopes can even see the shape of a cell, its nucleus, mitochondria and other organelles at the cellular level, allowing scientists to see the shape of a cell, its nucleus, mitochondria and other organelles. While a modern microscope has several components, the lenses

Several optical instruments have been designed using the concept of reflection, refraction, lenses, prisms and many more. Microscopes and astronomical telescopes are two of the most useful instruments. Microscopes allow individuals to see items that are not visible to the naked eye. On the other hand, telescopes are meant to observe distant, faint objects and
