Final answer:
In the equation for the magnetic field component of an electromagnetic wave, the quantities that appear include the electric field amplitude (E) and the speed of light (c), using the relationship B = E/c to relate the electric and magnetic field strengths.
Step-by-step explanation:
The question pertains to the quantities that appear in the equation for the magnetic field component of an electromagnetic wave. In electrodynamics, the magnetic field component B of an electromagnetic wave can be calculated using the relationship “B = E/c”, where E is the electric field amplitude of the wave, and c is the speed of light in a vacuum, approximately 3 x 108 m/s. When a plane electromagnetic wave moves in a certain direction, its electric and magnetic fields oscillate perpendicular to the direction of wave propagation and to each other, a characteristic of a transverse wave. The strength of the magnetic field is directly proportional to the electric field and inversely proportional to the speed of light.
For example, if an electromagnetic wave has an electric field magnitude of 6.0 V/m, the magnitude of the magnetic field B can be found using the equation B = E/c. Similarly, for a more complex expression such as E = (6.0 × 10⁻³ V/m) sin(27 × 1¹/m - ωt), the associated magnetic field can be derived using the same principle, adjusted for the wave's specific amplitude, frequency, and phase.
