Unformatted text preview: 85. Eq. 345 gives B = E/c, 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, the rms value of the
√
magnetic ﬁeld is 0.2/3 × 108 = 6.7 × 10−10 T, which (upon multiplication by 2) yields an amplitude
value of magnetic ﬁeld equal to 9.4 × 10−10 T. ...
