Final answer:
In arts, rhythm describes the regular repetition and movement of elements, creating a pattern that contributes to a work's visual effect.
Step-by-step explanation:
In arts, rhythm is the term used to describe the repetition and movement in which some or all elements repeat regularly. Rhythm creates a pattern through the systematic arrangement of shapes or forms, which can contribute to a lyrical or syncopated visual effect in a composition. This phenomenon is especially evident in physical forms, such as in a painting where bold and directional brushwork might convey the movement of waves crashing, or in the structured repetition found in a Buddhist mandala. Therefore, the answer to the question is 1) rhythm.
