Explain with the aid of a diagram the term fundamental note and overtone as applied to vibrating air in closed pipe.

When the air is brown into a pipe, it vibrates in many different modes, producing waves of different frequencies.

The fundamental note is the note of lowest frequency which  is dominant one

A fundamental note is formed by a wave of large amplitude and with a node N at the closed end and an antinode A at the open end.

Overtones  are the other notes of frequencies higher than that of the fundamental note  that are produced . They  have  usually low amplitudes and are less intense.
