When two waves of the same frequency and amplitude travel in opposite directions, they interfere with each other to form standing waves. This results in a pattern with fixed nodes where there is no displacement and antinodes where the displacement is maximum. Standing waves are characterized by their stationary pattern, as opposed to traveling waves. Transverse and longitudinal waves describe the direction of oscillation relative to wave propagation, while electromagnetic waves refer to a different type of wave phenomenon. Therefore, the correct answer is the formation of standing waves.

A transverse wave is characterized by oscillations that are perpendicular to the direction of wave propagation. This does not directly relate to two interacting waves traveling in opposite directions.

Longitudinal waves involve oscillations in the direction of wave propagation. The question, however, is about the result of two waves traveling in opposite directions, which leads to a different phenomenon.

Standing waves occur when two waves of the same frequency and amplitude travel in opposite directions, resulting in a wave pattern with nodes (points of no displacement) and antinodes (points of maximum displacement).

Electromagnetic waves are a separate category of waves that involve oscillating electric and magnetic fields. They are not specifically related to the interaction of two mechanical waves in a medium.
