Morphology
The literal image of moving one's hand is directly derivable from 'hand' + 'wave', so a B1 learner would understand it refers to a gesture. However, the idiomatic extension to mean a vague, insubstantial explanation or dismissive tactic is a metaphorical shift that is not fully predictable without exposure, making the expression only partially transparent.
Etymology
The phrase hand waving comes from the image of someone moving their hand in a waving way to draw attention or hide a problem. That's why it means giving 'vague' or 'distracting' explanations instead of a clear answer.
