A plane electromagnetic wave of frequency 25 GHz is propagating in vac

1.	A plane electromagnetic wave of frequency 25 GHz is propagating in vacuum along the z-direction. At a particular point in space and time, the magnetic field is given by vector B = 5 x 10-8 jT. The corresponding electric field vector E is (speed of light c = 3 × 108 ms–1)(1) 1.66 × 10–16 iV/m(2) 15 iV/m(3) -1.66 x 10-16 iV/m (4) -15 iV/m
Answer» Answer is (2) 15i V/m E/B = c E = B × c = 15 N/c Answer is (2) 15 iV/m E = vector (B x V) = (5 x 10^-8 j) x (3 x 10⁸ k) = 15 iV/m

Answer»

Answer is (2) 15i V/m

E/B = c

E = B × c

= 15 N/c

Answer is (2) 15 iV/m

E = vector (B x V)

= (5 x 10^-8 j) x (3 x 10⁸ k)

= 15 iV/m
