What type of pipe is characterized by one end being open and the other end closed?

A pipe that has one end open and the other end closed is known as a closed pipe. In acoustics, this configuration creates a specific series of resonances and standing wave patterns due to the boundary conditions imposed at the closed end, where there is a displacement node (minimum air movement) and at the open end, where there is a displacement antinode (maximum air movement).

In a closed pipe, the fundamental frequency is established, and only odd harmonics are present in the resulting sound wave series. This contrasts with an open pipe, where both ends are open, allowing for both even and odd harmonics. Understanding the behavior of sound in a closed pipe is fundamental in various applications, including musical instruments and acoustic engineering.

The other types mentioned do not accurately reflect a setup with one end closed and one end open. Therefore, the correct classification for a pipe that has one end open and the other end closed is indeed a closed pipe.
