Question

Item 12 Part A A 2.23-Hz simple harmonic wave is propagating in the negative z-direction at 35.0 cm/s A 2 23-Hz simple harmonic wave is propagating in the negative z-direction at 350 cm/s, Find a mathematical description giving the displacement y of this wave, in cm, as a function of position z and time t, where z is in cm and t is in s. Assume the displacement at z = 0 is maximum when Express your answer in terms of the variables r and t. Express the coefficients using three significant figures. with amplitude 2.87 cm. e2.87 sin (0.400329x-14.01151) (z,t)-2.87 sin (0.4003298-140115) an Submit My Answers Give Up Incorrect; Try Again; 2 attempts remaining Continue

Explanation / Answer

As the wave travelled in negative x-direction,

          y = A sin (kx-wt)

        y = 2.87 sin ( 0.4x + 14t) cm
