In the context of waves, an envelope refers to a smooth curve that outlines or envelops a set of oscillating waveforms. Specifically, it often describes the modulation shape of a wave packet or the amplitude variation of a group of waves. Here's a breakdown of the concept: 1. **Wave Packets**: When individual waves combine, they can interfere constructively or destructively. The resulting superposition can create a wave packet, which may have a varying amplitude over time.
