The amplitude of the magnetic field part of a harmonic electromagnetic wave in vacuum is `B_0=510 nT`. What is the amplitude of the electric field part of the wave?

Explanation

To find the amplitude of the electric field part of a harmonic electromagnetic wave in vacuum given the amplitude of the magnetic field, we can use the relationship between the electric field (E) and the magnetic field (B) in electromagnetic waves. The relationship is given by:

\[ E = c \cdot B \]

where:
- \( E \) is the amplitude of the electric field,
- \( B \) is the amplitude of the magnetic field,
- \( c \) is the speed of light in vacuum, approximately \( 3 \times 10^8 \, \text{m/s} \).
