I have a question dealing with sound waves.
This figure shows waves spreading radially outward from a coherent source located at the center. The center spot represents a coherent source emitting at a constant frequency. Black indicates maxima (positive peaks) and white indicating minima (negative troughs)
a) The source is a speaker emitting a pure tone. Quantitatively speaking, would you hear a different sound intensity at points A and
B?
b) Is the quality of the sound (the tone) dependent
on location? That is, would you expect a
qualitatively different sound at different
locations?
I remember that the intenesity of sound decreases as sound increases because as the wave spreads further from the source to the areas of low and high pressure respecitively gain and lose pressure (compressions and rarefactions)
So would this mean that the sound you hear at point B is more intense than the sound you hear at point A?
And thus the quality of the sound is dependant on location?
thanks for the help;
