Question

1) A transverse traveling wave is made on along slinky. The transverse displacement is given by D =0.94sin(8.7x + 72t), where D and x are in meters and t is inseconds. What is the wavelength (in m) of this wave? (Answer: 7.22x10^ -1) 2) A transverse traveling wave is madeon a long slinky. The transverse displacement is given by D =0.54sin(1.2x + 91t), where D and x are in meters and t is inseconds. What is the frequency (in Hz) of this wave? ( Ans:1.45x10^ 1 ) 1) A transverse traveling wave is made on along slinky. The transverse displacement is given by D =0.94sin(8.7x + 72t), where D and x are in meters and t is inseconds.

Explanation / Answer

Displacement D = 0.94 sin ( 8.7 x + 72 t )

Compare this with D = A sin ( kx + wt )

We get propagation constant k = 8.7

So, wavelength = 2(pi) / k
