dual nature of man

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 particle as well as a..

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..

Normal green house effect was principally dominated by H 2 O (vapour), CO 2 and O 3 the interception of infrared radiation by these gases was in the wavelength ranges as given below: Water vapour - 6 - 25 m m CO 2 - 13 - 17 m m O 3 - 9 - 10 m m Human activities have aggrevated the green house effec..

Natural Resources - The things that man derives from the environment are called natural resources. Natural resources are thus stores of supplies that are needed by man. The resources include the energy, air, soil, water, minerals, microbes, other or..

Sound is a form of energy. It is produced by the vibration of particles and it travels in a wave-like motion. The number of waves passing a point per second is called the frequency and its unit is Hertz (Hz). The pitch of the sound (high or low sounding) is measured by the frequency. Man..

. In the free state, carbon exists in both crystalline and amorphous forms. In nature, the two crystalline forms that exist are diamond and graphite. The amorphous forms of carbon do not exist naturally. They are either man made, or produced from organic matter. Amorph..

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 of particle..
