A) 520 m
B) 515 m
C) 530 m
D) 513 m
Correct Answer: D
Solution :
Time taken by sound to travel from the source to the reflecting surface, \[t=\frac{3}{2}=1.5\,s\] \[speed,v=342\text{ }m{{s}^{1}}\] \[\therefore \]Distance of reflecting surface from the source \[s=vt=342\times 1.5=513\text{ }m\]You need to login to perform this action.
