These sound waves depict the voices of a boy and girl.Can you identify the girls sound wave?
is there a way to comletely "cancel out" sound in a place ? (without creating a vacuum)
ls there any possibility to reduse the frequency of the sound?
is there a simple way to do "echo ranging" (without SONAR) , which we could try at home?
which are the lenths at which the bridges should be placed so as to get the fastest result in a sonometer?
Please give me some details about the "Interference" of sound, where you have two sound sources with both of then emitting sound at the same frequency there will be points in the space, where destructive interference takes place, will be completely soundless..
even if we shout from a car we here nothing outside. whereas if we open the glass a bit, we hear everything. sound travels through solids then why not?
