definition of dual nature of radiation and matter

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..

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 p..

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..

>Similar to light, matter also manifests itself in the form of particles as well as waves. Compton effect, and Davison and Germer's experiment stand as evidence for dual nature of matter. If an electron acts as a wave, its wavelength is calculated to be Davison an..

> is called the Stefan-Boltzmann constant after Josef Stefan (who discovered equation (ii) experimentally in 1879) and Ludwig Boltzmann (who derived it theoretically, later). The symbol e represents the emissivity of the object's surface, which has a value between 0 and 1, depending on the composit..
