Morphology
The meaning is directly compositional: a 'sine wave' is a wave that has the shape or pattern of the sine function, so a learner who knows 'sine' (the trigonometric function/curve) and 'wave' (an oscillation or repeating disturbance) can derive the combined meaning. Although technical, this modifier+noun pattern is standard in scientific vocabulary and is cross-linguistically transparent, making the expression predictable for learners who know the constituents.
Etymology
Sine wave comes from the math function sine, which draws a smooth up-and-down curve that looks like a steady wave. So sine wave refers to that smooth, repeating shape used for pure sounds and simple electrical signals.
