A) 0.1 m
B) 0.2 m
C) 0.4 m
D) 0.5 m
Correct Answer: A
Solution :
[a] \[\lambda =\frac{v}{n}=\frac{340}{170}=2m\], \[n'=\frac{340}{340-17}\times 170\] \[n'=178.9\,Hz\] Now \[\lambda '=\frac{v}{n'}=\frac{340}{178.9}=1.9\] \[\Rightarrow \,\lambda -\lambda '=2-1.9=0.1\]You need to login to perform this action.
