dual nature of radiation and matters

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..

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 p..

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..

>This is called as dual nature of mater. The radiation has a dual aspect behaving either as waves or as particles (waves when it interferes, diffracts and particles in a photocell). Einstein showed that a particle having a finite mass has been supposed to be ..

In 1896, the phenomenon of radioactivity was accidentally discovered by French scientist Henri Becquerel. He was performing experiments with uranium compounds. He accidentally placed a crystal of potassium uranyl sulphate over photographic plate wrapped with usual black paper. On developing the p..
