Question

how do the magnetic and electrical components of electromagnetic waves travel in relation to each other?
at right angles
toward each other
in a circular motion
parallel to each other

Explanation:

Electromagnetic waves consist of electric and magnetic field components. By the fundamental nature of electromagnetic waves, the electric field (electrical component) and magnetic field (magnetic component) oscillate perpendicular (at right angles) to each other and also perpendicular to the direction of wave propagation. The other options are incorrect: "toward each other" is not how they interact in terms of direction of oscillation, "in a circular motion" is not the relationship between the two components' oscillation directions, and "parallel to each other" contradicts the known properties of electromagnetic waves.

Answer:

A. at right angles
