Understannding About The Polarisation Of Light

The polarisation of light is significant for some types of optical applications. An optical plan often looks at the regularity and force of light, but not its polarisation. However, polarisation is still a fundamental property of illumination that affects even optical systems that can’t say for sure what it is. A light source can be […]

Ultraviolet Waves: Structure, Definition and Characteristics

A disturbance that travels through a medium is defined as a wave. This propagation is often explained using an equation. Some waves need a medium for propagation, while some do not necessarily require a medium. Ultraviolet waves are electromagnetic waves that fall in the latter category.  Ultraviolet waves are produced by high-temperature surfaces such as

Transverse nature of electromagnetic waves

An electromagnetic wave consists of an electric and a magnetic wave in which electric and magnetic field vectors are perpendicular to each other. Not only this, but they are also perpendicular to the direction of propagation of the wave. This nature of electromagnetic waves is known as the transverse nature of electromagnetic waves. Reflection: Reflection

Thread on Relation with Electric Current

Mechanical waves propagate through a medium, such as string, water, or air. The presence of consolidated electric and magnetic (or electromagnetic) fields that propagate through space as electromagnetic waves are possibly the most accurate prediction of Maxwell’s hypotheses.  Since Maxwell’s theories are legitimate in free space, the anticipated electromagnetic waves, unlike mechanical waves, do not

The Uses And Effects Of Photoelectric Effect

To understand the significance of the photoelectric effect, you need to understand the concept first. It refers to the phenomenon where the light rays hit the metal surface to release electrons from the metal. These ejected electrons are known as photoelectrons.  The emission of these photoelectrons and the ejected photoelectron’s energy are highly dependent on

The Rayleigh-Jeans Radiation Law

Latest: NEET 2024 Paper Analysis Recommended: NEET Rank Predictor 2024 See more: NEET Result 2024 The Rayleigh-Jeans Law of radiation gives us the intensity of radiation released by a black body. The law states that the intensity of the radiation emitted by a black body is directly proportional to the temperature and inversely proportional to the wavelength raised

The History of Photoelectric Effect

The phenomenon where electrically charged particles from the metal are emitted after it absorbs electromagnetic radiation is the definition of the photoelectric effect. The effect is described as electron ejection from a metal plate. It is one of the fundamental concepts in modern physics as it provides an answer to one of the most pressing

Radio Waves

Introduction Radio waves are Generally a type of electromagnetic radiation with the longest wavelengths in the electromagnetic spectrum, with a frequency of 300 gigahertz (GHz) and below. At 300 GHz, the corresponding wavelength is 1 mm (shorter than rice grains); at 30 Hz the corresponding wavelength is 10,000 km (longer than the radius of the

Polarisation

In 1808, Etienne Louis Malus (1775-1812) observed the birefringence of a piece of calcite while looking at two images of the setting sun, one faint and the other relatively bright. He suggested and related the word Polarisation to this property of light, the orientation of the preferred direction of light to the poles of the

Plane-Polarised Light

Introduction Light waves are called plane polarised light when they vibrate in one plane, and the direction of their electric field remains constant with their motion. Polarised light is produced during normal optical processes by bending light rays, including absorption, refraction, reflection, deflection (or distribution), and birefringence (same spot). The reflected light is usually partially
