Chapter 17, Problem 10P

To determine

To find

a) If the source is located at angle $\theta$ in front of you, what is $\Delta t$ in terms of $D$ and the speed of sound $v$ in air?

b) If you are submerged in water and the sound source is directly to your right, what is $\Delta t$ in terms of $D$ and the speed of sound $v_w$ in water?

c) Based on the time delay clue, your brain intercepts the submerged sound to arrive at an angle $\theta$ from the forward direction. Evaluate $\theta$ for fresh water at $20℃$.
