QUESTION 9The electric field in an electromagnetic (EM) wave traveling north oscillates in the east-westdirection.(a) Describe the direction of the magnetic field vector in this wave.(b) Describe the electric and magnetic field directions in the case where the EM wave isunpolarized.Note: If, instead of using geographic coordinates (north, south, etc.), you feel morecomfortable using cartesian coordinates (x,y,z), you may do so while assuming that the EMwave travels is the z direction.

(a) Given that direction of propagation of a EM wave is along z axes . Then the direction of…

Chapter 35, Problem 033 Your answer is partially correct. Try again. Three electromagnetic waves travel through a certain point P along an x axis. They are polarized parallel to a y axis, with the following variations in their amplitudes. Find their resultant at P. E1 = (3.0 x 10-5 v/m) sin[(2.0 × 1014 rad/s)t] E2 = (6.0 x 10-6 V/m) sin[(2.0 x 1014 rad/s)t + 45°] Ez = (6.0 x 10-6 V/m) sin[(2.0 × 1014 rad/s)t - 45°] E = µV/m ) sin[(l 2.00 x 1014 | rad/s )t + ° (degrees)

There is a vector defined by John Henry Poynting in 1884 whose direction gives the direction that an electromagnetic wave transmits its field energy and whose magnitude is the rate at which energy is being transmitted per square meter of the wavefront. For mutually perpendicular E- and B-fields in the wave, the magnitude of the Poynting vector is S =EB/mu0 and the direction is given by a right-hand rule, curling fingers from E vector and B vector. a) Carefully analyze the units of the Poynting vector and show that they are indeed watts per square meter. b) Find the intensity of the light in a beam of light whose electric field strength is 360 N/C and whose magnetic field is 1.2 muT.

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.
