Question

When the door of the Chapel of the Mausoleum in Hamilton, Scotland, is slammed shut, the last echo heard by someone standing just inside the door reportedly comes 15 s later. If that echo were due to a single reflection off a wall opposite the door, how far from the door is the wall?

Solutions

Step 1
1 of 2

We have the following given: $t=15\;\text{s}$ and $d=25.7\;\text{m}$. Since the echo was due to one reflection, this means that the sound has covered the distance from the door to the wall twice. Therefore, we have:

$D=(n+1)d=v\times t=343\times 15=5160\;\text{m}$

Where d is the distance from the door to the wall.

$d=5160/2=2580\;\text{m}$

Notice that we have substituted with $n=1$ as the sound reflected only once.
