Do fiber optic transmits the radiation?
Light is a radiation; hence, the answer is yes. Several fibers, depending upon the nature of the materials from that they are made, transmit one band of radiation more or less extensive or limited. Usually, the fibers used for lighting transmit some or no ultraviolet, variable quantities of the visible light frequencies and a very small amount of infrared light frequencies.
Heat is a radiation on the infrared area and does not transmit fine on standard lighting fibers. To put an illustration the amount of heat which will build up inside a case with a volume of one cubic meter of air, it is only one degree in 24 hours, by a 5mm diameter PMMA light guide powered through a 150W metal halide illuminator.
When a metal becomes a superconductor, there is a tremendous decrease in it's: a) Total volume b) Electrical resistance c) Length d) Density Ans: While a
In forced oscillation of a particle, the amplitude is maximum for a frequency ω1 of the force while the energy is maximum for a frequency ω2 of the force, then what is relations
Define Radioactive Dating Half-life measurements of radioactive elements in rocks and fossils can be used to determine the age of the specimen. One of the most common types of
Determine q, q = ax2¬- 2by + c2z2 where a, b and are c are constant at (1, -2, 3)
Resistance: Resistance is the opposition to the motion of electrons. This arises as a result of collision of moving electrons. The unit of resistance is "ohm" represented by
why we use compensater??
For a parallel-plate capacitor with plate area "A" and plate separation "d", the capacitance is proportional to which of the following? a) A divided by d squared b) A tim
Q. A transistor is connected in CE configuration. The voltage drop across the load resistance ( Rc) 3 k is 6 V. Find the base current. The current gain α of the transistor is 0.97.
Superposition principle The general idea is that, while a number of influences are working on a system, the total influence on that system is just the sum of the individual in
