What is the purpose of a clapperboard?

Explanation:
A clapperboard provides a precise synchronization cue between audio and video. When it’s snapped, the clap is a clear visual moment on the camera and a sharp sound in the microphone, creating a matching point editors can align in post-production. This makes it possible to perfectly sync multiple takes and cameras, even when sound was recorded separately. The board also carries scene and take information to keep footage organized, but its main purpose is to enable accurate audio–video alignment. It isn’t used to measure lighting or to record sound itself.
