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.
Q The refractive index of a medium is √3. Compute the angle of refraction if the un-polarised light is incident on it at the polarizing angle of the medium. μ = tan i p = √3
In a certain cathode-ray tube, a beam of electrons, moving at a constant velocity, enters a region of constant electric force midway among two parallel plates that are 10.0 cm long
Force: Force may be defined as a push or a pull upon an object. In the English system the pound (1b) is used to express the value of a force. For example, we say that a force
All the given four Laws may be written in one relation, PV = nRT =m/n RT This formula is known as deal gas equation. Where m = mass of the gas M = molecular mass of t
Demerits of Semiconductor Diode over Vacuum Diode (i) It can't withstand high reverse voltage (ii) It can't operate at fairly high temperatures.
The fringe width in a Young's double slit arrangement is 0.008cm. What could be the fringe width if the slit separation is halved and the screen slit distance is doubled?
