Concave Mirror When a hollow sphere is cut into certain pieces and the exterior surface of the cut part is painted, it becomes a mirror, with the interior surface reflecting light. As a result, you’ll have a concave mirror. A concave mirror, also known as a converging mirror, is a mirror that is turned inwards […]

Total internal reflection occurs due to the refraction of light. When light travels from one medium to another the direction as well as the speed of light changes. This phenomenon is known as the refraction of light. The driving force of refraction is change of optical density of the medium. Optical density and real density

The deviation of light occurs when a beam of light changes route as it travels from one medium to another. Refraction occurs twice when a ray of light passes through a prism. It enters and exits the prism twice. Light rays bend towards the normal while passing from an optically rarer media to an optically

Introduction The bending of light beams at the meeting point of two transparent media is known as refraction. This is due to a shift in the direction of the light wave as well as the bending of light waves at the media’s meeting point. Refraction  through a spherical surface happens when the speed of a

The behaviour of light, as a rule, depicts the conduct of apparent, bright, and infrared light. The experiment is demonstrated by Young’s double-hole experiment, or the modern, two-hole experiment, or the double-hole experiment, that both light and matter exhibit properties of both wave and particle. Apart from this, the experiment also shows the probabilistic nature

X-rays were discovered on 8 November 1895 by a German Physicist Wilhelm Conrad Roentgen. X-ray is defined as an electromagnetic radiation having very short wavelength and having very high energy. The frequency of X rays are ranging from 30 petahertz (101015 Hz) to 30 exahertz (301018 Hz).  The wavelength of X-rays is longer than the

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
