# If the speed of sound in water is 1480 m/s and a pirate ship is trying to

Fantastic news! We've Found the answer you've been seeking!

## Question:

- If the speed of sound in water is 1480 m/s and a pirate ship is trying to locate a treasure lost on the floor of the ocean, how far down would they have to dive to retrieve the treasure? Keep in mind they are using a sonar device (these are advanced pirates) and the sound wave takes 4.0 s to travel the entire distance.
- Two of the pirates, Mac and Tosh, are sitting in their own dinghies that are 25 m away from each other. Mac dives in and creates a surface wave that takes 25 s to travel to Tosh and back to his own dinghy. What is the speed of this wave?
- If each adjacent wave crest is 6.0 m apart and splashed on Tosh's dinghy upon reaching him, how much time passes between each successive wave (the frequency) hitting Tosh?
