There are two bottles of glass, one bottle is two-third filled with water and another bottle is filled one third with water. When we blow across the mouth of each bottle, then
(i) The bottle with the less air in it gives the note of the higher pitch
(ii) The shorter the air column, the higher the pitch of the note produced.
Answers
Answer:
yes te statement is true
Answer:
Most wind instruments work on the principle that the shorter the air column, the higher the pitch of the note produced.
Therefore both options (i) and (ii) are correct and option (i) is the correct explanation of option (ii).
Explanation:
Shorter instruments have shorter air columns and thus standing waves with shorter wavelength produces higher pitches.
When working with waves the wavelength and frequency (pitch) are inversely proportional.
Sound waves have the relation frequency times wavelength equal to the speed of sound.
Wind instruments use a longitudinal dimension of air in the instrument as a medium like a "string". In both the string and wind instruments, shorter wavelengths in the exciting medium (string or column of air) emit higher frequencies.
