Question

does the speed of sound waves change due to the density

Answer 1

Yes, the speed of sound waves does change due to the density of the medium through which they are traveling. In general, sound travels faster in denser materials, such as solids, than in less dense materials, such as gases. This is because the particles in denser materials are closer together, allowing sound waves to travel more quickly through them. In contrast, sound waves travel more slowly through less dense materials because the particles are further apart, leading to a slower propagation of the waves.
