the nature of matter electrons

An electron is defined as a subatomic particle which carries one unit of electrical charge (1.602 x 10 - 1 9 C) and has a mass (9.1 x10 - 2 8 g). The mass of an electron is almost negligible, being 1/1837 t h the mass of an atom of hydrogen. The charge of an electr..

The Photoelectric Effect - 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..

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 well as a wave. It ..

>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..
