The element was discovered by Lord Raleigh and Sir William Ramsay in 1894. Argon is the third most abundant element in the atmosphere. Its concentration in air is 0.934% by volume. Also, it occurs in earth s crust at a concentration of 3.4 mg/kg, and in the sea water at 4.3 pg/L. It was most likely formed in earth crust by radioactive decay of K-40 and seeped out into the... 

Black polymers, such as polyacetylene, absorb all visible light, but opaque polymers scatter the incident light. As shown by Lord Raleigh, the turbidity r is related to the scattered light per unit volume, integrated over all angles.

The phenomena of uniform drop formation from a stream of liquid issuing from on orifice were noted as early as 1833 by Savart [2] and described mathematically by Lord Raleigh [3,4] and Weber [5]. In this type of system that is based on their observations, fluid under pressure issues from an orifice, typically 40-80 pm in diameter, and breaks up into uniform drops by the amplification of capillary waves induced onto the jet, usually by an electromechanical device that causes the pressure oscillations to propagate through the fluid. The drops break off from the jet in the presence of an electrostatic field called the charging filed, and thus acquire an electrostatic charge. The charged drops are directed to their...
