Der Umgang mit unseren Fehlwahrnehmungen,wave generated by the antenna decreases inversely with distance as one moves away from the antenna, i.e., the signal decreases as 1/., where . is the distance from the antenna to the point of observation. However, if the conductivity of the ground is finite, then the amplitude of the radio wave decr

Weltweite Sorge, nicht weltweites Netz, along the ground surface and forms circular loops with the center at the point of strike (Fig. 13.1). At any given point the magnetic field is parallel to the tangent to the circle describing the magnetic field. Thus the direction of the magnetic field gives the direction to the point of a lightnin
