/c to photons of energy h u . The elastic scattering of a photon from an electron at rest can be worked out by using the principles of conservation of energy and conservation of momentum. The discovery in 1905 of the dual nature of light was followed by the discovery of dual nature of matter. Even..

Superposition of two waves of the same frequency traveling in the same direction, giving rise to a sustained interference pattern. Superposition of two waves of slightly different frequencies traveling in the same direction, giving rise to the phenomenon of beats. S..

In 1856, James Clark Maxwell proposed that light and other forms of radiant energy propagate themselves in the form of waves, through space. These waves have electric and magnetic fields associated with them and are called electromagnetic waves or electromagnetic radia..

The ability of the instrument to resolve the images of two point objects lying close to each other. Due to the wave nature of light each point object produces its own diffraction pattern, which overlap, and the image can no longer be identifie..

Electroencephalography - Brain cells can generate electrical activity as a result of literally millions of action potentials of individual neurons. These electrical potentials are called brain waves and indicate activity of the cerebral cortex. Brain waves pass through the skull..

. These impulses are transmitted from the electrodes to a recording pen that graphs the impulses as a series of up and down waves called deflection waves. 3 recognisable waves accompany each cardiac cycle. The first called the P wave, is a small upward w..

Principles of Light Modulation - Let us consider the case of electromagnetic radiation in an ionised medium. Suppose we increase/decrease the amplitude of an electromagnetic wave passing through an ionised gas. These modulations of the electromagnetic wave could contain coded in..

Summary - The basis of life on earth is atmospheric cover on earth and natural cycles like carbon, oxygen, nitrogen and hydrological cycles. Atmosphere is evolved in its present form due to sunlight and rotation of earth on its axis. Many environmental changes like change in rainfall pattern..

The ability of the instrument to resolve the images of two point objects lying close to each other. Due to the wave nature of light each point object produces its own diffraction pattern, which overlap, and the image can no longer be identified. Resolving power of a microscope i..

1. During constructive interference R m a x = A + B as cos f = + 1 During destructive inference cos f = -1 R m i n = A - B special case If A =B (i.e., if the two waves have same amplitude) then This indicates a good contrast between the bright and dark bands, which is..
