A) 16.6 cm
B) 10.0 cm
C) 20.0 cm
D) 33.3 cm
Correct Answer: C
Solution :
Speed of wave \[=\text{ }\sqrt{\frac{T}{\mu }}=\text{ }\sqrt{\frac{\frac{8}{5\times {{10}^{-3}}}}{1}}\] \[=\,\,\sqrt{\frac{8\times {{10}^{3}}}{5}}\,=\,40\,m/s\] \[v=F\lambda \] \[\lambda \,\,=\,\,\frac{40}{100\,\,}\,metre\] Distance between two consecutive node \[=\frac{\lambda }{2}=\frac{20}{100}\,\,metre\,\,=\,\,20\,cm\]You need to login to perform this action.
