What are basic attenuation mechanisms in a fibre?
The fundamental attenuation mechanisms into a fibre are as follows:
a. Absorption
b. Scattering (Mie and Rayleigh scattering)
c. Radiation losses
d. Connection or coupling losses
Stefan-Boltzmann constant; sigma (Stefan, L. Boltzmann) The constant of proportionality exist in the Stefan-Boltzmann law. It is equivalent to 5.6697 x 10 -8 W/m 2 /K 4 .
The delay in regaining the original state by a body after the removal of the deforming force is known as elastic after effect. In electrometers and galvanometers, the suspension
1 OHM: If a potential difference of 1 volt is applied across the ends of a conductor and the resulting current flowing by the conductor is 1 ampere, the resistance of the condu
How can we ger plane polarised light??
Write down the condition for dispersion without deviation. Describe power of a lens. What do you mean by magnification?
suppose you are running and want to stop at once. surely you will have to produce negative acceleration in your speed. can you tell from where does the necessary force come ?
#what are practical examples of like and unlike parallel forces?#
Their conductivity lies between conductor and insulator. Their resistivity is usually high and temperature coefficient of resistance is always negative. These are materials which a
