Properties of electromagnetic waves

Electromagnetic waves, or EM waves, are produced by vibrations between an electric field and a magnetic field. In other words, electromagnetic waves are made up of oscillating magnetic and electric fields. Electromagnetic waves are created when an electric field interacts with a magnetic field. As a result, they are referred to as ‘electromagnetic’ waves. An […]

According to the definition of electromagnetic radiation, they are a form of radiant energy and comprise electromagnetic waves. The waves are formed due to the continuous oscillation of magnetic and electric fields. The oscillations are periodic changes occurring in the magnetic and electric fields. Moreover, electromagnetic waves move at the speed of light in a

Electromagnetic waves are naturally present in EM radiation. The frequency of oscillation may be used to define the position of an electromagnetic wave within the electromagnetic range. A changing magnetic field at a certain spot creates an electric field at the same moment, according to Faraday’s electromagnetic induction. Many physics-related articles provide information about electromagnetic

In early days our ancestors used to cook their food by sitting around smoky wood fires for hours to cook their food. But nowadays we need to press some buttons and put food inside the micro-oven and we just need to wait for 2 – 5 minutes and our meal gets ready to eat. Microwaves

Unpolarised light can be transformed into polarised light. Light waves that are polarised have oscillations of electric fields that occur in a single plane. Polarisation is the process of converting unpolarised light into polarised light. Polarising light can be done in a variety of ways. The four methods are –  Polarisation by Transmission Polarisation by

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

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

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

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

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
