We know that the magnetic ﬁeld points
along the −y axis, so we just need to ﬁnd the
magnitude, which we can do using
c= 2 , . c=
we can write
E =c B
= (3 × 108 m/s)(4.3 × 10−5 T)
= 12900 N/C . B= c
3 × 108 m/s
= 9.5 × 10−6 T . dedow (kfd235) – Ch24-h1 – turner – (56525)
So the y component is −9.5 × 10−6 T . Correct answer: 0 T.

At a time t0 , an electric ﬁeld is detected in
the region shown on the left diagram in the
ﬁgure below. The electric ﬁeld is zero at
all other locations. At a later time t1 , an
electric ﬁeld is detected in the region shown
on the right diagram. The electric ﬁeld is
still zero elsewhere. You conclude that an
electromagnetic wave is passing through the
region. The +z direction points out of the
page (toward you).
t0 y x netic wave is propagating in the −y direction.
