(d) We choose the minus sign (between kx and ω t ) in the argument of the sine function because the wave is shown traveling to the right [in the + x direction] – see section 16-5). Therefore, with SI units understood, we obtain y = y m sin( kx kvt ) 0.0030 sin(16 x 2.4 ¡ 10 2 t ) . 11. (a) The amplitude y m is half of the 6.00 mm vertical range shown in the figure, i.e.,

Unformatted text preview: 3.0 mm. m y = (b) The speed of the wave is v = d/t = 15 m/s, where d = 0.060 m and t = 0.0040 s. The angular wave number is k = 2 / where = 0.40 m. Thus, k = 2 = 16 rad/m . (c) The angular frequency is found from = k v = (16 rad/m)(15 m/s)=2.4 10 2 rad/s....
