Sound does not travel in a vacuum. It needs a medium in which to travel (unlike light) and so sound cannot travel in a vacuum. However, in a solid sound travels faster than in air.
light at least i do an average of 260millisecond to light and 350 to sound
Light and sound both move in waves. Light is much faster than sound. Light waves are smaller than sound waves.
A wine glass makes a noise when you run your finger along the rim because of vibration. Your finger rubs against the glass and sets up vibrations because of friction. The glass crystals are "frozen" into a solid and are lined up all in one direction inside the glass. When the rim vibrates, the ripples spread all over the glass, and the bell-shape of the glass focuses the sound back out the top. Voila - sound.
1.Think of a sound 2.make sure that sound in your head is audible 3.Project that sound outside your head

sound travels faster through a solid than through air
sound travel faster through soled because of tighter packed particles
Sound waves transmit sound through a solid, as well as air and water. Sound waves cannot be transmitted through a vacuum.
Sound travels faster through air. Though sound travels farther through solid objects (vibrations), it is faster when traveling through air waves.
Faster.
Solid
Sounds travel faster in solid materials than any other materials.
Sound travels faster through solid materials. The 2nd fastest is liquids.
Sound moves through a solid faster than anything. In order it goes, solid, liquid, and gas. So metal is faster than water is faster than air.
Sound travels faster through some solid because, in general, the particles are packed more closely together. This transfers the sound wave faster. Other solids do not transmit sound well at all.
Generally, sound moves faster through a solid than through a liquid. This is because the molecules of a solid are more condensed than those of a liquid. However, sound does not move faster through all solids than through all liquids.1
Sound travels by vibrating through matter (solid, liquid, gas) A vacuum is the absence of matter and with out matter there is nothing for sound to travel through
