Amplitude of magnetic field of an electromagnetic wave in a vacuum,
B0 = 510 nT = 510 × 10−9 T
Speed of light in a vacuum, c = 3 × 108 m/s
Amplitude...
(a) in vacuum
(c) in a material medium
EXPLANATION:
The light is an electromagnetic wave that can travel in a vacuum as well as in a transparent material medium.
(i) Standard equation of magnetic field is
By = B0sin(ωt + kx)T
Comparing this equation with the given equation, we get
B0 = 8 x 10-6T, ω = 2 x 1011 rad s-1, k...
