i think this thread should be renamed to "adi' questions" .....i think i will fill this whole thread with just my question
okk..so here i go again..
The definition of sound energy is "longitudinal pressure waves that travel through a compressible material"
now my question is that sounds travel through solids...but solids are incompressible...
another addition....sounds waves are a series of compressions and rarefactions....in air, they compress the air molecules...but how do they do that i solid???
