Triangles Can be Solved Using: 1  Pythagoras's Theorem. 2  Sine Rule. 3  Cosine Rule. 4  Angles all add up to 180 degrees.
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.
According to Physics Web in 'Sound breaks the light barrier,' a professor of physics in Tennessee has designed an experiment which proves that sound can move faster than light. This looks like impossible -- and it is. In fact, the physicist has tweaked some scientific definitions. No sound can go faster than light. But a sound pulse, or more precisely, all the wavelengths associated to a sound, have a group velocity that far exceeds the real physical limits.
