Final answer:
The symbol used to represent yin and yang is known as Taiji or Taijitu, which illustrates interconnected and interdependent forces in the natural world.
Step-by-step explanation:
The symbol used to represent yin and yang is known as (a) Taiji, sometimes spelled as Tai Chi. This symbol, also referred to as the Taijitu, is composed of a circle divided into a black section and a white section, each containing a dot of the opposite color. It represents the concept of dualism in ancient Chinese philosophy, illustrating how seemingly opposed forces are actually interconnected and interdependent in the natural world, and how they can give rise to each other as they interrelate.
Yin, represented by the black part of the Taiji symbol, is associated with attributes such as shadows, femininity, and passivity. Yang, represented by the white part, corresponds to brightness, passion, and activity. Despite their differences, yin and yang are not absolute contrasts; they are relative to each other and contain the seed of their opposites, showing the dynamic and cyclical nature of existence.
