SUMMARY

Acoustic resonance can be produced in a 32 cm long tube when a sound wave with a wavelength of 20 cm is introduced. The condition for resonance requires that the doubly-reflected wave aligns closely with the original wave, specifically within 1/4 wavelength. If the ends of the tube are open, resonance is achievable, as open tubes support both odd and even harmonics. The discussion emphasizes the importance of understanding wave behavior in relation to tube length and wavelength for effective resonance.

PREREQUISITES
  • Understanding of acoustic resonance principles
  • Knowledge of wave behavior in tubes
  • Familiarity with wavelength and frequency relationships
  • Basic concepts of sound wave reflection
NEXT STEPS
  • Research the principles of acoustic resonance in open and closed tubes
  • Study the relationship between wavelength, frequency, and tube length
  • Learn about harmonic series in acoustic systems
  • Explore practical applications of resonance in musical instruments
USEFUL FOR

Acoustics students, sound engineers, musicians, and anyone interested in the physics of sound and resonance phenomena.

I need help with a question about acoustic resonance.

Sound of wavelength 20cm is produced at one end of a 32 cm long tube. Is it possible for resonance to be produced?
 
Physics news on Phys.org
The condition for re-sonance is for a doubly-reflected wave
(now traveling the same direction as the original wave)
to be "almost in-step" with that original wave
"close to" an integer number of wavelengths back.

"close to" effectively means closer than 1/4 wavelength,
because 1/2 wavelength excess leads to total cancellation.

Did they say whether the ends of the tube were open or closed?
