The colour of pure cadmium sulphide is pale yellow. It melts only under at high temperature. It can be prepared in the resistivity range from 10 to about 1012Ω-cm depending on the presence of defects and the impurities. it can be prepared as an semiconductor device and is extremely difficult to produce P-type cadmium sulphide. It has been used commercially as a photo conductor for many years as well as constituent of cathode ray phosphorous.
Magnetic lines of flux A line of flux is a line indicating the direction in which a free north pole would travel, if placed in the field at that point. Alternatively it
Q. Find the minimum wavelength of X-rays produced by an X-ray tube operating at 1000 kV. λmin = 12400 A 0 / V Therefore λmin = 12400 X 10 -10 / 10 6 = 0.0124 A 0
Surface tension is a contractive tendency of the surface of a liquid that permits it to resist an external force. It is revealed, for instance, in the floating of some objects on t
