Optics

The lens is a transparent medium that is bordered by two surfaces, at least one of which must be curved in order for the lens to function. When the distance between the two sides of a lens is exceedingly short, it is said to be thin. When a lens has a positive focal length, it […]

Lens formula Introduction A lens is a transmissive optical device that can focus or disperse a light beam using refraction. A simple lens consists of a transparent material. There are two main types of lens: convex lens and concave lens. We will learn about them in detail. Glasses or plastics make lenses, and they are

Zinc sulphide is one of the most common phosphorescent materials. Phosphorescent is a particular type of photoluminescence. Unlike fluorescent substances, phosphorescent material emits focused energy at once. In fluorescence, the desire is instant and generally only visible if the light source is continuously on, such as a UV light. At the same time, phosphorescent material

Understanding ellipses can help in comprehending the mathematics behind four-dimensional objects. An ellipse is a geometric object that serves as the location of the two foci of a set of circles specified by a parameter. It is a curve in a plane surrounding two focus points and has a constant distance between any point on

Thin-film interference occurs when a lightwave is reflected off two surfaces separated by a distance equal to its wavelength. We witness distinct coloured patterns when light waves that reflect off the top and bottom surfaces collide. During this process, light strikes the border between the two media. With some of it being reflected and some

Introduction The eye is a complex organ. It allows animals to view the world around them and the objects in it. Whether the objects are far or near, eyes allow us to see and place them. Eyes also allow us to see and process various shapes and colours. In some ways, the eye is like

The eye may develop visual problems for a variety of causes, including injury, excessive TV viewing, using a mobile device to view a computer screen from a close distance, lens degeneration, or even aging. The malfunctioning of the lens has resulted in a few flaws. One is myopia (short-sightedness) and the other one is hypermetropia

As we know that eyes play a very crucial role in our life. The human eye is the most valuable and sensitive part of the human body. It helps us to identify the different colours. There is no doubt that by closing our eyes, we can identify the objects around us to some extent only

A spherical mirror is a unique type of mirror in that it has a round edge. This type of mirror is often used in photography because it gives a more flattering view. Spherical mirrors are often used in architectural and engineering applications because they are less reflective than traditional mirrors and allow a broader range

Increasing the distance between the object and the mirror causes the object’s size to increase until it reaches its original size. A concave mirror is characterised by a reflecting surface that is recessed inwards. The mirror also converges the light to a single point of focus, which is why they are also referred to as
