dual nature

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..

Summary - The phenomenon of interference, diffraction and polarization can be explained by the wave theory of light. But the photo electric effect can be explained only using 'photon theory'. That is using particle nature of light. The experimental study of photoelectric effect led to the..

In 1924, de Broglie's suggested that all material objects including an electron have a dual character; they behave as particles as well as waves. The wavelength associated with a particle of mass 'm', moving with velocity 'v' is given by de Broglie's relation as: The discovery of the w..

According to Max Planck's Quantum theory, radiation is not continuous but is made up of tiny packets of energy called photons. However, this theory could not explain other optical phenomena. From all the above theories it is clear that certain optical phenomena can be explained clearly only if ligh..

It could not explain the line spectrum of multi electron atoms. This model failed to explain the effect of magnetic field on the spectra of atoms (Zeeman effect). The effect of electric field on the spectra could not be explained by Bohr's model (Stark effect). The shapes of molecules ar..

Characteristics of Light - Light is a form of energy produced by luminous objects. Light can travel through vacuum. Light can penetrate through transparent materials but cannot pass through opaque objects. Light travels in a straight line in an optically homogeneous medium. Light bounces back when ..
