Vedclass · Answer

(A) To hear an echo,the sound must travel to the reflecting surface and back to the source,covering the distance twice.Given:Speed of sound $(v)$ = $342 \,m \,s^{-1}$Time taken $(t)$ = $3 \,s$Total distance traveled by sound $(2d)$ = $	ext{speed} 	imes 	ext{time}$$2d = 342 \,m \,s^{-1} 	imes 3 \,s = 1026 \,m$Therefore,the distance of the reflecting surface from the source $(d)$ is:$d = 1026 \,m / 2 = 513 \,m$.

An echo is heard in $3 \,s$. What is the distance of the reflecting surface from the source,given that the speed of sound is $342 \,m \,s^{-1}$ (in $,m$)?
