Yes, panflutes traditionally have cork plugs in some of their holes to help create different notes and tones by changing the length of the vibrating column of air. These cork plugs can be moved to adjust the pitch of the instrument.
The bassoon is a double-reed woodwind instrument that uses a system of keys and fingerings to produce different pitches. When air is blown through the reed, the vibrations create sound waves that resonate in the instrument's long, coiled body. By pressing down on various keys and holes, the player can change the length of the vibrating air column, producing different notes.

The instrument used to measure Earth's circumference is called a theodolite. It is a precision instrument that measures horizontal and vertical angles. By measuring angles between points on Earth's surface, scientists can calculate the size of Earth.
there are many instruments used to measure length depending upon the size of object , Ruler is Metric instrument used to measure length. Screw gauge is also used as an instrument used to measure length in mm.

Lower. By increasing the length of the air column in the instrument, the wavelength of the sound produced is longer, resulting in a lower pitch.
The pitch is changed on a Trombone by moving the slide or changing your ombisture.
The flute can produce multiple octaves by changing the way air is blown into the instrument and by using different fingerings to change the length of the vibrating air column. This allows the player to produce higher or lower pitches across different octaves.

In a brass instrument, sound is produced when the player buzzes their lips into the mouthpiece. This buzzing creates vibrations, which then travel through the air column inside the instrument. The shape and length of the instrument, along with the player's technique, affect the pitch and tone of the sound produced. Valves or slides may be used to change the pitch by altering the length of the air column.
