Question

Name one factor which affects the frequency of sound emitted due to vibrations in an air column.

Answer 1

Hint: As per the question, the frequency of sound depends on how much the area or length of the air column is. Frequency is inversely proportional to the length of the air column. As length is minimum then the frequency gets higher.

Complete answer:
Length of the air column affects the frequency of sound emitted due to vibrations in the air column.
The length of the air column is a factor that determines the frequency of sound. The frequency falls as the length of the air column increases.
As a result, the length of the air column is one-fourth of the first harmonic wavelength. The fundamental frequency is the lowest frequency that any instrument can produce; it is also known as the instrument's first harmonic.
The length, diameter, tension, and density of the string are the four parameters that influence its frequency. When a string's length is adjusted, it vibrates at a different frequency. Strings with a shorter length have a greater frequency and, as a result, a higher pitch.
The fundamental wavelength of the tube is twice its length (or \[160{\text{ }}cm\] ). Resonant frequencies for open-open air columns are whole number multiples of the fundamental frequency. The fundamental must be \[200Hz\] if the tube produces \[600Hz{\text{ }}and{\text{ }}800Hz\] (with no notes in between).

Note:
The actual frequency is determined by the qualities of the object's material (which impacts the wave's speed) and the material's length (this affects the wavelength of the wave).
The frequency of the sound source determines the pitch of a note. The frequency is measured in Hertz (Hz), with one hertz equaling one vibration per second ( \[1{\text{ }}Hz\] ). A high frequency results in a high-pitched sound, while a low frequency results in a low-pitched note.
