A) a
B) \[\frac{a}{2}\]
C) \[\frac{a\sqrt{3}}{2}\]
D) zero
Correct Answer: A
Solution :
The figure shows variation of displacement of particles in a closed organ pipe for 3rd overtone. For third overtone \[\ell =\frac{7\lambda }{4}\,\,or\,\,\lambda \,\,=\,\,\frac{4\ell }{7}\,\,or\,\,\frac{\lambda }{4}\,\,=\,\,\frac{\ell }{7}\] Hence the amplitude at P at a distance\[\ell /7\] from closed end is ?a? because there is an antinode at that pointYou need to login to perform this action.
