physics- atomic radiation

The first and only atomic bombs were used in war was in 1945 when Hiroshima and Nagasaki were devastated. Widespread destruction and damage were produced immediately by the blast. Some of the damage caused by the emitted radiation became evident within days, but some did not be..

Dangers of Radiation - The first and only atomic bombs were used in war was in 1945 when Hiroshima and Nagasaki were devastated. Widespread destruction and damage were produced immediately by the blast. Some of the damage caused by the emitted radiation became evident ..

Bohr's Theory of Hydrogen Atom - Niels Bohr suggested that the problem about hydrogen spectrum can be solved if we can make some assumptions. According to classical theory, the frequency of the electromagnetic waves emitted by a revolving electron is equal to the frequency of revolution. ..

Conclusion - Rutherford's alpha particle scattering experiment explained the structure of atom and the size of nucleus. The Bohr's model explained the hydrogen spectrum. Radioactivity occurs due to nuclei being unstable resulting in the emission of three types of radiations havi..

. As the radiating energy of a revolving electron (according to classical electromagnetic theory) continuously decreases the electron should follow a spiral path and fall into the nucleus. So this atomic model could not account for the stability of the atom. The observ..

>When a nucleus emits radiation it is said to decay. Rays from radioactive isotopes are dangerous to living things but are also useful in variety of ways. Exposure to large amounts of radiation is harmful to health. All radioactive materials should always be handled with care an..

A star is a dense cloud of hydrogen and helium gas contracting under its own gravitational pull. In all the stars hydrogen atoms are continuously converted into helium atoms and this process is accompanied by a large amount of energy. This energy is radiated in t..

It is a nuclear phenomenon. It is due to the instability of the nucleus. It is a spontaneous, continuous and irreversible process. It is independent of external factors such as pressure, temperature, state of substance, electrical field, magnetic field, catalyst etc. A radioactive ele..

/p. This is de Broglie wave equation. De-Broglie's hypothesis attributing a dual particle-wave character to matter appears very strange at first sight. Since it is very much against the direct evidence of one's senses at the macroscopic level. But at the level of the atom, the behavior of..
