Optics

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

Refraction Refraction, in physics, the change of the wave path from one medium to another due to its change in speed. For example, waves move faster in deep water than in the top. If the ocean waves approach the coast in a perpendicular direction, part of the wave farther from the sea will move faster

Knowing that light is a kind of energy, we may see that it can experience a variety of phenomena such as diffraction, reflection, refraction, interference, polarisation, and polarisation among others. When light moves from one medium to another, it experiences refraction, which occurs as a result of the bending of the light. Refraction In wave

A lens is a homogeneous transparent medium such as glass bounded by two curved surfaces or one curved and one plane surface. The curved surface may be cylindrical, paraboloidal or spherical, but most surfaces are spherical. A simple lens is made up of just one transparent element, whereas a compound lens is made up of
