Sound Wave Propagation

Sound waves propagate faster through solids than gases, right? But they also travel faster through less dense media? Aren't solids more dense than gases? I'm confused.

There are two bordering media with equal resistance to compression but different densities. A sound is then transmitted through the two media. Which of the following statements is true about this scenario?

A The sound will travel faster through the medium of higher density.
B The sound will travel faster through the medium of lower density.
C The sound will travel at the same speed through the media.
D The sound will travel faster through the medium of greater mass.

a denser medium slows down sound waves!

proportional to bulk modulus, inversely proportional to density of medium.

this is the equation you want : v = √(β/&#96😉. So a sound wave's velocity is directly proportional to bulk modulus while inversely proportional to density.
