Answer #1

Solution)

a) We will have nodes because at closed ends nodes are present n organ pipies.

=========

b) wavelength of fundamanetal harmonic,

L=lamda/2. Simce it is closed at both ends

so , lamda=2.80 * 2=5.6 m

=======

c) speed of sound=343.2 m/s

We also know,

v=lamda*frequency

so frequency=v/lamda=343.2/5.6=61.28 hz (Ans)

=========

d) Here, first overtone

L=1*lamda

lamda(1)=2.80 m

2nd overtone

L=1.5*lamda

so

lamda=2/3*2.8=5.3/3=1.866 m (Ans)

========

Acc to HOMEWORKLIB RULES, I can answer these many parts at a time.

Good luck!:)
