Question

                                where Bx = 3.9 X 10-6 T, By = 4.7 X 10-6 T, and i-hat and j-hat are the unit vectors                                 in the +x and +y directions, respectively.

i only need the answers for 2,3,4

                                        1)                                     

                                        2)                                     

                                        3)                                     

                                        4)                                     

                                5)                             

                                where BIIx = 4.7 X 10-6 T, BIIy = 3.9 X 10-6 T, and i-hat and j-hat are the unit                                 vectors in the +x and +y directions, respectively.                             

Explanation / Answer

solution :

1) speed of a wave is given by v=?f

so, f = c / ? = (3*10^8 m/s) / (3.4*10^-2 m) = 0.88235 * 10^10 Hz = 8.8235 *10^ 9 Hz = 8.8235 GHz

2) Intensity for an E-M wave is given by:

0.5*c*?0*E2 = 0.5*c3*?0*(Bx2+By2)

E2 = c2*(Bx2+By2)

E = sqrt((3*108)2*((3.9*10-6)2 + (4.7*10-6)2)) = 1832.212 W/m2

3) Magnitude can be given by c*(Bx2 + By2) /
