A) The wavelength of wave is 4 cm.
B) The maximum displacement of free end of rod about mean position is 3 cm.
C) Every point on rod performs SHM.
D) maximum displacement of free end is zero.
Correct Answer: A
Solution :
Resultant wave, v Maximum displacement \[=2A=6\,cm\] Total length of rod \[\ell =\frac{\lambda }{2}+\frac{\lambda }{2}+\frac{\lambda }{4}=\frac{5\lambda }{4}\] \[\Rightarrow \] \[\lambda =\frac{4\times 5}{5}=4\,cm\]You need to login to perform this action.
