I hypothesize that the friend will hear the bell faster in the pool than in the air. This is because sound travels faster in water than in air due to water being denser, allowing sound waves to move more quickly through it. Therefore, the time taken for the sound to reach the friend should be shorter in the pool.

In one or two sentences, make and justify a hypothesis on which medium the friend would hear the bell the fastest.(2 points) Put in very simple words and put in 2-5 sentences
