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.
Write down the Maxwell's electromagnetic wave equations both in differential form.
How is radiation emitted from the body? The body radiates energy by thermal conduction by the skin to the air, clothes, etc, around the body. A small amount of energy would als

Assume we place a screen with two parallel slits right in front of a lens (with focal distance f ), and illuminate with light (at wavelength λ) from far away. (a) What will be the
Q. Why the centre of Newton's rings pattern appears dark? The thickness of the air film becomes zero at the point of contact of lens L with glass plate P. Therefore there is no
This depends on the arrangement of a beam or column. for a simply supported beam with a point load in the centre of the beam Mmax = WL/4 and will occur at centre span W is the lo
Is it possible to construct a vibration magnetometer at home?? If yes then what all materials will i require ? Also what is the working principle of the vibration magnetometer?
