Sine Wave Symbol
The ∿ symbol represents a sine-wave pattern and is useful for describing periodic motion and signals.
U+223F
∿ is the “sine wave” symbol in Unicode. It’s commonly used in math, engineering, and UI text to suggest periodic, oscillating behavior. You can copy it directly or use its HTML, CSS, and JavaScript escapes.
Sine Wave Symbol Meaning
The character “∿” (Unicode name: SINE WAVE, U+223F) is a typographic marker associated with wave-like, repeating motion. Visually, it resembles a wavy line that helps readers recognize oscillation or periodic signal behavior at a glance. In math or technical writing, it can appear near formulas, graphs, or labels to suggest sinusoidal functions. In design and interface copy, it can represent “wave” concepts such as sound, vibration, or smooth rhythmic movement. Use it as a compact, recognizable alternative to writing “sine wave” repeatedly in headings, legends, or annotations.
Common uses
- •Labeling sinusoidal charts or waveform legends in diagrams
- •Representing periodic motion or oscillation in scientific and engineering notes
- •Adding a wave icon to UI text for audio, signal, or vibration settings
- •Marking “sine wave” in presentations, worksheets, and math study materials
- •Designing math-themed graphics, posters, or infographics where a wave symbol is needed
