(a) Name one factor on which the frequency of sound emitted due to vibration in an air column depends.
(b) How does the frequency depend on the factor stated in part (a)?
(a) Name one factor on which the frequency of sound emitted due to vibration in an air column depends.
(b) How does the frequency depend on the factor stated in part (a)?

(a) The length of an air column is affected by the frequency of sound released owing to vibration in the air column.

(b) As the length of the air column grows longer, the frequency drops. As a result, we may conclude that they are inversely proportional, i.e. f is inversely proportional to l.
