. Similarly, if the radiations given out by a radioactive substance are subjected to an electric field perpendicular to their path, they separate into three constituents. Those which turn towards the negative plate are the positively charged alpha particles. Those, which turn towards the positive p..

The study of structure of atoms, radioactivity, X-ray, diffraction, etc., in physics has enabled chemists to rearrange elements in the periodic table and to have a better understanding of chemical bonding and complex chemical structure..

Similar to the crystal diffraction patterns produced by X-rays, even the beam of electrons of appropriate momentum could produce crystal diffraction pattern..

The discovery of the electron towards the end of the nineteenth century was the starting point of new avenues of research in science, which were to give physicists an insight into the structure and nature of the atoms of matter. In 1896, Henri Becquerel discovered that when a photographic..

It is also called Nuclear Magnetic Resonance (NMR) spectroscopy as it is based on this phenomenon. It is a diagnostic technique that provides high quality cross-sectioned two or three - dimensional images of organs without having X-rays or other radiation..

Calculation of Density of a Cubic Crystal from its Edge Length. The edge length of a cubic crystal can be obtained from X-ray studies and knowing the crystal structure possessed by it so that the number of particles per unit cell are known, the density of the crystal can be calculated..

These are waves that can pass through vacuum in addition to passing through matter. In other words, a material medium is not necessary for their propagation. They consist of periodic variations of electric and magnetic fields at right angles to each other and also at right angles to the direction ..

Summary Atom is the smallest particle of an element, which maintains its identity throughout chemical and physical changes. Atoms are made up of three fundamental particles: electrons, protons and neutrons. Discharge tube experiments by William Crookes and J.J. Thomson led to the di..

While all electromagnetic waves travel at the same speed (i.e., velocity 'c' is constant), the type of their radiation differs in the duration of wavelength and consequently their frequencies. An electromagnetic radiation with a long wavelength will have a low frequency and vice versa. 'The arra..
