In astronomy, the low temperature microwave radiation that arrives at the earth's surface from all directions of outer space is called background radiation. It is so named because it forms a background to all the radio sources that have been detected by radio telescopes. Cosmic ..

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 ..

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 ..

Tungsten carbide (WC) is used for making cutting drilling tools. Silicon carbide (SiC) is used as an abrasive and refractory material. SiC is also called carborundum. Boron carbide (B 4 C) is harder than silicon carbide, and is used as an abrasive and as a shield again..

. The remnants of such pesticides used on pests may get adsorbed by the soil particles, which then contaminate root crops grown in that soil. The consumption of such crops causes the pesticides remnants to enter human biological systems, affecting them adversely. An infamous herbicide ..

. Thus, they are not likely to do much damage unless they enter the body on contaminated food etc. b - particles have a greater range, but they too are easily absorbed and a Perspex screen may be used as protection. g - rays are most dangerous because of their high penetrating power, and ..

There are a small number of radioisotopes of low proton number, which occur naturally. They are produced by bombardment by radiation from outer space (cosmic rays). The most well known of these is radioactive carbon-14, which is produced when nitrogen is bombarded by neutron..
