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.
Earth is losoing heat in order balance the input outpout . But where is going that heat since there is nothing out to get it. Billions of stars are loosing heat the same way and so
Define Elasticity
If a traveling wave is a sin or cos function of (x± vt) the wave than it is said to be harmonic or plane progressive wave.
Q. What is a power? Answer: That seat of EMF" reply is SO wrong. Not merely is the rate of charge delivery not power but a seat of EMF doesn't deliver charge. A seat of EM
A forced harmonic oscillator is at resonance with some periodic force. Evaluate the phase difference between the driving force and the velocity of the oscillator?
Q. Define: the temperature coefficient of resistance. The ratio of raise in resistance per degree rise in temperature to its resistance at 0 o C is called as temperature coeff
Super conductivity has long been a staple of science fiction one of the first mentions of the phenomenon occurred in Robert A Heinlein’s novel “Beyond this Horizon (1942)”. Notably
A) Explain the flow of direct current? ( describe direct current) b) Explain the effect of resistance in circuits? (Describe effect of resistance)
if a big person and a small person run up the stairs in the same time, which of them develops the most power
Consider an electron in a simple one-dimensional periodic potential. The energy of the electron will vary periodically due to the influence of the periodic potential, and can be de
