GALLIUM PHOSPIDE: It has band gap of 2.3ev. it can be used for light emitting diodes which can emit green or red light. The red light is obtained with zinc or cadmium oxide doping.
SELENIUM: It is found in crystalline and non-crystalline form. It is used as rectifier material for photo voltaic cells and for xerographic printing. Selenium films are used as photo electric light meters. Its melting point is 2200C.
LEAD: it is soft heavy and bluish gray metal. It is highly resistant to many chemical actions but can corrode by nitric acid, lime and rotten organic substances. Lead and its compounds are toxic. It is mechanically weak it cannot withstand vibrations at high temperatures. It alloys easily with Tin and zinc and forms many commercial alloys, including solders and bearing metals.
Materials which can be magnetized are called magnetic materials. When magnetized, such materials create a magnetic field around them. Some of the significant features of magnetic m
What is Fission and Fusion? Fission: The breaking down of a Nucleus (not atom) into minute nuclei. It is usually induced by a neutron. For instance, a Helium nucleus (known a
The lead alloy: Most of the soldering in the electronic industry is carried out using tin lead alloy. Pure lead metals at 327 0 C, whereas tin melts at 232 0 C and the mixture of
Factors on which Magnetic Force Depends: The magnetic force depends on following factors: 1. Nature of Pole: Like poles repel each other and unlike pole attract each other.
Q. A 4.5cm needle is placed 12cm away from a convex mirror of focal length 15cm. Give the location of the image and the magnification. Describe what happens as the needle is moved
if in an interference pattern,the ratio between maximum and minimum intensities is 36:1,find the ratio between the amplitude and intensities of the two interfering waves.
Why the velocity of light is limiting velocity of anything.
Gauss' law for magnetic fields (K.F. Gauss) The magnetic flux by a closed surface is zero; no magnetic charges present; in differential form, div B = 0.
A person is determining the description of the image formed by a converging lens by implies of a ray tracing diagram. The person has gotten so far as drawing one principal ray. Wha
Why because it is not a source as Li-ion battery. If we want to measure the voltage(build in voltage) with in the diode we have to use the external source. We can''t directly measu
