Two atoms re-radiate in response to an incident sinusoidal electromagnetic wave (which is not shown). Define the +x direction to the right, + y direction upward, and +z direction outward. Wavefronts illustrate the peak electric field in the +z direction due to the re- radiation of each atom in the xy plane. (Figure 23.51 in the textbook illustrates both the wavefronts and the electric and magnetic field vectors associated with the wavefronts at various locations around a sinusoidally oscillating charge.) Six locations in space along the midline between the atoms are labeled 1 through 6. The electron's acceleration in each atom is mostly affected by the incident radiation, and the influence of re-radiation by one atom on the other atom is negligible. Part 1 Your answer is incorrect. Select all locations where the net electric field due to the re-radiation of both atoms is in the + z direction. 1 2 3 + 5 10 6

A 2.0C charge moves with a velocity of v = ( 2i + k) m/s in a region where both auniform magnetic field B= (2i - 3k) T and a uniform electric field E = (2i -3j) V/mexist. Calculate the total force on the moving charge.

An excited hydrogen atom releases an electromagnetic wave to return to its normal state. You use your futuristic dual electric/magnetic field tester on the electromagnetic wave to find the directions of the electric field and magnetic field. Your device tells you that the electric field is pointing in the positive x direction and the magnetic field is pointing in the negative y direction. In which direction does the released electromagnetic wave travel?

A current of (1.124x10^0) A is used to charge a parallel plate capacitor with square plates. The side of each plate is (6.0160x10^1) cm. What is the displacement current through a (4.31x10^-3) m² area wholly between the capacitor plates and parallel to them? Answer with three significant figures in mA.

the amplitude of the magnetic field of a plane electromagnetic wave is 1.41x10^-12 T. Calculate the amplitude of the electron field

A sample of helium gas is excited with an electric current, which causes the helium to emit electromagnetic radiation when the helium atoms return to their ground state. You measure the maximum magnitude of the electric field of the emitted radiation to be 0.0074 V/m. Based on your measurement, what is the maximum magnitude of the magnetic field in the radiation?

Consider regions of the EM spectrum. In order to study the structure of a crystalline solid, you want to illuminate it with EM radiation whose wavelength is the same as the spacing of the atoms in the crystal (0.190 nm). A) What is the frequency of the EM radiation in Hertz? B) In what part of the EM spectrum (radio, visible, etc.) does it lie?

Around the core of a nuclear reactor shielded by a large pool of water, Cerenkov radiation appears as a blue glow (see figure below). Cerenkov radiation occurs when a particle travels faster through a medium than the speed of light in that medium. It is the electromagnetic equivalent of a bow wave or a sonic boom. An electron is traveling through water at a speed 7.2% faster than the speed of light in water. U.S. Department of Energy/Photo Researchers, Inc. (a) Determine the electron's total energy.
