A) 3.0 nT
B) 4.0 nT
C) 5.0 nT
D) 6.0 nT
E) 7.0 nT

Question

Quizplus · Accepted Answer

The maximum value of the magnetic field associated with the electromagnetic wave can be determined using the relationship:
B = E/c
where B is the magnetic field, E is the electric field, and c is the speed of light.

Substituting the given values:
B = 1.5 V/m ÷ 3.0 x 10^8 m/s
B = 5.0 x 10^-9 Tesla or 5.0 nT

Therefore, the maximum value of the magnetic field associated with the wave is 5.0 nT. Option C is the correct choice.
