Eventually wouldn't it collapse in on itself and create black hole.
Answer: Mechanical waves
Explanation:
Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave. Sound waves are incapable of traveling through a vacuum.
#1
For closed pipe the fundamental frequency will be given as
#2
For open pipe the wavelength for Nth harmonic will be given as
#3
for a closed pipe the frequency is given as
here for third harmonic n = 3
now plug in all values
#10
since in the given figure there are three complete loops
so in this case the <em>number of harmonics are THREE</em>
