particle nature of electromagnetic radiation

The third mode of energy transfer between an object and its environment is via electromagnetic waves (visible light is a kind of electromagnetic wave). Energy transferred in this way is often called thermal radiation, to distinguish it from electromagnetic si..

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 the experimental facts..

>Three types of radiation from recognized radioactive elements are a -particles, b -particles and g -radiation. It was realized that radioactivity of an element is independent of its physical state, its chemical environment or temperature, suggesting that it ..

In 1900, Max Planck presented the results of his famous black body radiation experiments, which showed that light has a dual character, behaving like a particle as well as a wave. He gave the Quantum Theory of Radiation explaining electromagnetic radiat..

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 electromagnetic radiationh..

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 consists o..

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..
