A rodof half the length vi-brates longitudinallywith double the ra-pidity, a rod of one-third the length wTithtreble the rapidity, and dso on. The time ofa complete vibrationbeing that… … 106 SOUND. Tins division of a rod by a single node at its centrecorresponds to the deepest tone produced by its longi-tudinal vibration.
