speaker is placed at the end of a 1.3 m tube with both ends open. Sketch the two lowest modes.

A wire under a tension of 81N has a natural frequency of 256Hz. If the tension is raised to 121N.What will be the new frequency. ii.How many overtones can be found between 200Hz and 1024Hz for a wire whose fundamental frequency is 200Hz.

Imagine a ringing bell set inside a sealed glass jar. Once all the air is removed and a vacuum is created, the ringing sound is no longer heard. Explain why this happens.   The glass prevents any sound from escaping.   The pressure of the outside air causes the sound to remain within the jar.   The lack of air in the jar causes the ringing to stop.   Without air, the sound waves cannot travel to the ear.
