Hi all, As sound travels through air, does the air molecules travel with the same speed as well? In other words, if sound is travelling in air at 340m/s, does it also then mean that the mean speed of all the affected air molecules is 340m/s? I personally do not think so. I guess that the speed of air molecules will be greater than 340 m/s, but i do not know how to explain. Nor am i totally sure. Fellow forummers can help me please?
