dual nature of electromagnetic waves and how they travel in a vacuum

An electromagnetic wave is a disturbance, which does not require any material medium for its propagation and can travel even through vacuum. They are caused due to varying electric and magnetic fields. Radio waves and light waves are exa..

; in other words, these waves can pass through vacuum They require medium for propagation i.e. these waves cannot pass through vacuum All electromagnetic waves travel with the same velocity Matter waves travel..

Electromagnetic Nature of Light - In 1856, James Clark Maxwell proposed that light and other forms of radiant energy propagate themselves in the form of waves, through space. These waves have electric and magnetic fields associated with them and are called ..

Light has been regarded as waves to explain the phenomena of reflection, refraction, diffraction etc. However in 1905, Albert Einstein suggested that light has a dual character, which means, it can behave as a particle as well as a wave. It was observed that some of th..

Dual Nature of Matter and Radiation - Light has been regarded as waves to explain the phenomena of reflection, refraction, diffraction etc. However in 1905, Albert Einstein suggested that light has a dual character, which means, it can behave as a particle as..

In 1856, James Clark Maxwell proposed that light and other forms of radiant energy propagate themselves in the form of waves, through space. These waves have electric and magnetic fields associated with them and are called electromagnetic waves or ..

Depending upon their propagation in a medium, the waves are classified as follows: Mechanical waves or elastic waves and Electromagnetic waves..

Superposition of Waves - When a number of similar waves pass through a medium simultaneously, each wave travels through the medium as though the others were not present. However, at any point in the medium, the net effect of the waves reaching that ..

The suggestion that matter may have wave like properties was first put forwarded in 1924-1925 by Louis De Broglie. He argued that if light, which consists of waves according to classical picture, can sometimes behave like particles, then it should be possible for matter, which ..

When light of sufficiently small wavelength is incident on a metal surface, electrons are ejected from the metal. This phenomenon is called as 'photoelectric effect' and the ejected electrons are called as 'photoelectrons..
