A) 16.5 m
B) 33 m
C) 165 m
D) 330m
Correct Answer: B
Solution :
Monosyllabic sound reaches the listener after reflection in\[\frac{1}{5}s\]. Distance between source and listener is \[d=v\left( \frac{t}{2} \right)=330\times \left( \frac{1}{2}\times \frac{1}{5} \right)\] \[d=330\times \left( \frac{1}{10} \right)=33\,m\]You need to login to perform this action.
