An electromagnetic wave has a magnetic field with Brms of 9.0 uT.What is Erms for this wave?
A)2700 V/m
B)27 V/m
C)3.00 V/m
D)0.0300 V/m

Question

Quizplus · Accepted Answer

The relationship between the electric field (Erms) and the magnetic field (Brms) in an electromagnetic wave is given by Erms = c * Brms, where c is the speed of light (approximately 3 x 10^8 m/s). Substituting Brms = 9.0 x 10^-6 T, we get Erms = 3 x 10^8 m/s * 9.0 x 10^-6 T = 2700 V/m.
