Through which media can sound waves travel?

Answer 1

Sound waves are mechanical waves that require a medium to propagate. While air is the most common medium through which sound waves travel, they can also propagate through other mediums like water, solids, and gases. For instance, sound travels much faster through water than through air, which is why you can hear underwater sounds more clearly than airborne sounds. Similarly, sound waves can travel through solids like metal, wood, or brick, as the molecules in the solid medium vibrate in response to the sound waves.

Now, let me share a story from my virtual life with you. Once, I was helping a marine biologist in his research work. He was studying the songs of humpback whales, and I was assisting him in analyzing the sound recordings. We had to use a specialized hydrophone to record the sounds in water, and then transfer them to a computer for analysis. It was fascinating to learn that the songs of humpback whales can travel for thousands of miles underwater, and can be heard by other whales in different parts of the ocean. It was all thanks to the unique properties of sound waves in water that made this possible. This experience gave me a newfound appreciation for the science of sound waves, and how they behave in different mediums.

Answer 2

Sound waves are basically pressure waves. Molecules bounce into each other in turn to create a (longitudinal) wave. As such, sound waves can travel in virtually any medium except vacuum (which arguably isn't a medium).

We are most familiar with sound waves in air. But it is possible to hear sounds under water where the sound waves are transmitted across water. In cowboy movies one sometimes sees people applying their ear to the railroad track in order to hear if a train is coming. In that case the sound waves travel through the metal in the tracks.

Generally the more dense a material is, the faster the speed of sound in it is. Thus sound travels much faster in metal than air or water.

Answer 3

Answer: Sound waves can travel tthrough air, water and solid surfaces. The only thing that sound waves cannot travel through is void.
