Waves in a Large Pool

APPH12-G9Y7N2

While sitting in a large pool that has a wave generator situated in the center, you text your friend (because that is what you do in a large pool), who is sitting much closer to the wave generator.

If the amplitude of the generated wave is $A$ at your friend's location from the generator ($d$ $=$ $5.0$ $m$), what is the amplitude of the wave at your location farther away ($d$ $=$ $50$ $m$)?

Assume the pool is very large such that the reflection and superposition of waves is not a factor.

A

$10$ $A$

B

$3.16$ $A$

C

$0.1$ $A$

D

$0.316$ $A$
