WebObjects in the universe send out an enormous range of electromagnetic radiation. Scientists call this range the electromagnetic spectrum, which they have divided into a number of categories. The spectrum is shown in Figure 5.6, with some information about the waves in each part or band. Figure 5.6 Radiation and Earth’s Atmosphere. WebIn the case of electromagnetic waves, the penetration of the waves in matter varies, depending on the frequency of the radiation and the electric conductivity of the medium. The skin depth δ (which is the distance in the conducting medium traversed for an amplitude decrease of 1/e, about 1/3) is given by.

As given above, this results in the static field becoming insignificant compared to the EM field forces as the distance from the source is larger and it is neglected. Energy can be carried only by EM field or a wave and can't be carried by a constant static field. اضرار ارتفاع pt
