Report Abuse. sound travels fastest in solid substances. as in solids, the medium is denser and it aids the propogation of sound. sound will not travel in vaccum as they will not propogate if no material medium is present. in air it travels with the speed of 350 m/s which is less than the speed of sound in solids.
The time difference that you sense is due to the way sound and light travel. Light travels extremely fast (300,000,000 m/s). In fact, it is faster than anything else. Sound travels at a measly 343 m/s through air. Therefore we can see light in an instant, but it takes a while to hear thunder. Sound has another disadvantage because it tends to bounce off molecules in the air. This makes the sound travel in all different directions.
