Final answer:
To measure both ID and hole depth of a pipe when creating a musical instrument, a telescoping gauge and a depth gauge are normally used. Precise calculation and calibration are essential to ensure accurate pitch, which can be fine-tuned with the help of tuning forks.
Step-by-step explanation:
When considering an instrument that can measure both internal diameter (ID) and hole depth, a tool known as a telescoping gauge combined with a depth gauge is typically used.
In the context of creating a musical instrument such as a pipe, accurate measurements for the resonant frequency are crucial.
To calculate the length required for a certain frequency to resonate, one must consider the speed of sound in the material and the harmonic relationships. Once the length is calculated, positions where holes should be placed in the pipe to achieve the desired pitches can be marked.
For the calibration of these holes, a hand drill would suffice to make the initial holes, which can then be tuned using tuning forks. The holes' positions and diameters must be precise to ensure the correct pitch is achieved when the pipe is demonstrated.
