Unformatted text preview: 73. (a) Eq. 34-5 gives E = cB , which relates the field values at any instant – and so relates rms values to rms values, and amplitude √ values to amplitude values, as the case may be. Thus, Erms = cBrms = 16.8 V/m. Multiplying by 2 yields the electric field amplitude Em = 23.7 V/m. (b) We use Eq. 34-26: I= 1 2 E 2 = 0.748 W/m . µ0 c rms ...
