Which aspect of a waveform does an oscilloscope primarily display?

Explanation:
An oscilloscope visualizes how a signal's voltage changes over time. The vertical axis shows voltage amplitude, and the horizontal axis represents time, so you can see the waveform’s shape, amplitude, and timing features like rise time and period. Frequency isn’t shown directly; it’s inferred from the time base by measuring how long one cycle takes. Current would require a separate sensor, but a standard oscilloscope displays voltage versus time.
