Answer:
Certainly! Here is a diagram showing the path that a sound wave from above the surface would have to take to reach your ear if you are underwater:
Air → Water → Ear
Step-by-step explanation:
As the sound wave travels from above the surface, it first passes through the air and then enters the water. When the sound wave enters the water, its speed changes because the density of water is greater than the density of air. This causes the sound wave to refract or bend as it enters the water. The sound wave then travels through the water until it reaches your ear.
The muffled quality of the sound is due to the fact that water absorbs sound more effectively than air does. This means that some of the energy of the sound wave is lost as it travels through the water, making the sound quieter and less clear when it reaches your ear.
I hope this diagram and explanation helps you understand how sound waves travel from above the surface to your ear when you are swimming underwater!
