Sound is a compression wave that travels via then vibrations of particles. If the particles are closer together then the wave (sound) moves faster. Particles are closer together in a liquid than a gas, therefore sound travels faster through liquids.
Frequency and speed of propagation of the wave are independent of one another. The medium determines the speed of propagation.
refrction
water Dense solid objects
The wave will move faster, increasing its speed.
For a sound wave to be created there has to be a vibration
The light will either be absorbed, or it will pass through.

Light wave travels fastest in air Sound wave travels fastest in solid or liquid
Sound is vibration transmitted through a solid, liquid, or gas. To see sound waves as longitudinal waves in air moving, scroll down to related links and look at "Longitudinal wave - Wikipedia".
The frequency, as observed by the receiving end, will be less than the frequency at which the wave was emitted.
sound
The speed of sound through a solid depends upon the density of that solid. The denser the solid, the quicker sound travels.
"medium"
Solid, Liquid and Gas... These are the three things a sound wave can get trough... A sound-wave can get trough solid easily, because of all the particles, after that trough Liquid and at least trough Gas...
It becomes louder. The amplitude of the sound wave increases
