Witness optic information get sent through water by sending and receiving sound at either end

https://itp.nyu.edu/networks/explanations/fiber-optics-cables-for-information-exchange/

Description

This project is like a functional fiber optic data link but instead of fiber, the lightwaves travel through water using the same principle of total internal reflection. Each link is a speaker-microphone pair that allows for listening and speaking at either end. Basic receiver circuits will be built with a phototransistor, op amps, and a speaker. Basic transmitter circuits will be built with a laser, op amps, and a microphone.
