Reflection, refraction

Wavefront and Huygens’ principle. Introduction The link between waves and light rays is the subject of wave optics, also known as physical optics. When the wave qualities of light are taken into account, it is utilised. It is concerned with studying diverse phenomena such as polarisation, diffraction, interference, and other occurrences when rays cannot represent […]

Wave optics Introduction Physical optics, often known as wave optics, is a discipline of optics that examines interference, diffraction, polarisation, and other phenomena for which the geometric optics ray approximation is not applicable. The relationship between waves and light rays is well described by wave optics. Light is a kind of energy that flows through

The power of a lens determines the divergence or convergence of light produced by the lenses. This power of the focal point lens is the digression by which it meets or separates a light emission falling at a unit far off from the optical focus. The power of a lens can be positive or negative

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 (depressed inwards, diverging light rays). Cameras, binoculars and telescopes all employ lenses. Magnifying glasses must be known to you. A single convex lens with a frame makes

Every day we come across plenty of spherical surfaces unknowingly. But, we hardly realise how amazingly it works. For example, the spectacles you are wearing, the vehicle mirror you have, everything comes with a spherical surface. A change in the light direction or just a bending in the light wave moving from transparent mediums is

What is Total Internal Reflection or TIR The Total Internal Reflection is an optical characteristic of light where a beam of light propagates from an optically denser medium (e.g. water) into an optically rarer medium(e.g. air) at an angle of incidence greater than the critical angle for the two media separated at the interface is

Lenses are part of a transparent spherical mirror. They disperse light by the phenomenon of refraction — the process by which light rays deflect while passing from one medium to another medium). Lenses can be primarily of two types: Convex (converging) lens and Concave (diverging) lens. Silvering the surface of such lenses causes the formation

Light is a sort of energy that creates a vision in our eyes and helps us view different objects in our surroundings. Luminous objects are those that generate light on their own. The Sun, a light bulb, a tube light, glowworms, and so forth. Non-luminous items are those that reflect light from other sources. They

The ratio of the speed of an electromagnetic wave in a vacuum to its speed in another medium is referred to as the refractive index. It denotes the amount of refraction that might occur in a given substance. The normal can be defined as the perpendicular line to the interface’s surface. In this situation, a

Introduction We see a variety of objects in the world around us. However, we are unable to see anything in a dark room. When any object reflects the light that is incident on it, this reflected light shows us the object around us. In the world, there are wonderful phenomena related to light such as
