Unformatted text preview: with points on a sphere of radius r in phase. If is the angular frequency and k is the angular wave number then the time dependence is sin( kr t ). Letting b = p P/ 4 C , the displacement wave is then given by s ( r, t ) = r P 4 C 1 r sin( kr t ) = b r sin( kr t ) . (b) Since s and r both have dimensions of length and the trigonometric function is dimensionless, the dimensions of b must be length squared....
