If a musical instrument such as a trumpet or flute is "flat", should the pipe be lengthened or shortened? Explain

The pipe should be shortened.

Explanation:

Instruments like trumpets or flute works on the concept of sound waves. When the air is blown from the hole then due to different wave frequencies longitudinal sound waves generate.

Pipe with shortened length generate higher frequency inside the tube hence generating high or more sound. That is the reason why, musical instrument like trumpet or flute should be shortened if it is flat.

If a trumpet or a flute is flat, the pipe should be shortened to increase the pitch of the sound.

Explanation:

Musical instruments such as trumpet or flute work on the concept of sound waves. A flute or trumpet acts like a hollow tube with some holes. When the air is blown inside it, longitudinal sound waves are produced due to different wave frequencies.

If we reduce the length of the pipe; it produces higher frequency inside the tube. Whereas, longer tubes create sound waves of lower frequencies, generating low sound.

Hence, the length of a flute or trumpet should be shortened if it's flat.
