Please show work and experience explain
An 800 kHz radio signal is detected at a point 2.1 km distant from a transmitter tower. The electric field amplitude of the signal at that point is 800 mV/m. Assume that the signal power is radiated uniformly in all directions and that radio waves incident upon the ground are completely absorbed. The intensity of the radio signal at that point is closest to: A) 8.5 times 10^-4 W/m^2 B) 6.0 times 10^-4 W/m^2...

800 kHz radio signal is detected at a point 3.2 km distant from a transmitter tower. The electric field amplitude of the signal at that point is 690 mV/m. Assume that the signal power is radiated uniformly in all directions and that radio waves incident upon the ground are completely absorbed. The average total power radiated by the transmitter is closest to:...

2. A student passes light from a tube of hydrogen was passes light from a tube of hydrogen gas through a diffraction grating, resulting in discrete spectral lines. One of the lines has a wavelength of 186 nm with a width of 15 nm. This corresponde an energy and uncertainty of E = 2.55 +0.05 eV. Which transition between H energy levels could Produce this liner What energy is required to excite the hydrogen atom from the ground state In...

You place two antennas 5.00 m apart, each broadcasting a 1632.0 MHz radio signal, in phase with each other and uniformly in all directions. (Radio waves move at the speed of light.) You then study the intensity at various points the same distance from the midpoint between the antennas, a distance that is very large relative to the separation between the antennas. Measuring angles from a reference line that passes through this midpoint and is perpendicular to a line segment...
