Q: What kind of waves travel through liquids and solids as well as air?


Read this paragraph and choose the correct option from the provided answers:

Sound waves can travel through many different kinds of matter. Most of the sounds we hear travel through air, but sounds can also travel through liquids such as water and solids such as glass and metal. If you swim underwater — or even submerge your ears in bathwater — any sounds you hear have traveled to your ears through water. You can tell that sounds travel through glass and other solids because you can hear loud outdoor sounds such as sirens through closed windows and doors.
