Reflection and refraction

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 utilized. It is concerned with the study of diverse phenomena such as polarization, diffraction, interference, and other occurrences when geometric optics cannot be represented […]

The fact that matter is made up of waves is one of the most counter-intuitive facts in physics. In this lesson, you learned about both the particle and wave natures of light, as well as how they interact. You are aware of the Photoelectric effect resulting from Albert Einstein’s generosity. In the photoelectric effect, electrons

The link between waves and light rays is the subject of wave optics, also known as physical optics. It is concerned with studying diverse phenomena such as polarisation, diffraction, interference and other occurrences when rays cannot represent geometric optics.  The branch of optics that deals with the behaviour of light and its wave characteristics is

When we talk about UV spectroscopy or UV–visible spectrophotometry, we’re talking about absorption spectroscopy or reflection spectroscopy in the ultraviolet and neighbouring visible parts of the electromagnetic spectrum. This means that it makes use of light that is visible and next to it. The absorption or reflectance of the chemicals involved in the visible spectrum

The Tyndall effect is the scattering of light by particles in a colloid or a very fine suspension of particles in a liquid. In addition to being known as Tyndall scattering, this phenomenon is similar to Rayleigh scattering in that the intensity of scattered light is inversely proportional to the fourth power of the wavelength,

A complete reflection of a beam of light from the surrounding surfaces back into a medium such as water or glass is known as total internal reflection. When the angle of incidence exceeds a particular limiting angle, known as the critical angle, the phenomena happen. Total internal reflection occurs when a ray of light from

Internal reflection often occurs when  a light beam or ray travels from a denser medium to a rarer or less optically denser medium.  In such a phenomenon, two things happen. A portion of the incident light gets reflected into the same medium. In contrast, another part gets refracted into a different medium.  When the angle

Violet, indigo, blue, green, yellow, orange, and red are the seven colors that the sun breaks into. It’s commonly referred to as VIBGYOR. When all of these hues are combined, we only receive one light that  is the WHITE light. It is feasible to create the band of seven colors using white light and a narrow

Introduction The index of refraction, also called the refractive index, is a measurement of how much a ray of light bends as it passes through one medium and into another. If ’i’  is the angle of incidence for a ray in the vacuum (the normal is the angle formed by the incoming ray and the

Refraction is an observational phenomenon that occurs with a ray of light. In simple terms, it is called the bending of light rays when they go from a single transparent substance to another transparent substance.  Refraction happens with several things around us, including eyeglasses, lenses, water, sound, and other waves. This bending results in the
