Question: a snusodal wave moving along a string is shown twice...

Question details

A snusodal wave moving along a string is shown twice in Figure 16-32, as crest A travels in the positive direction of an x axis by distance d = 3.25 cm in 42.0 ms. The tick marks along the axis are separated by 2.5 cm. 6.0 mm Figure 16-32 The wave equation is of the form below. y(x, t)-y,sin ( kr ± w t) Include SI units for all answers. Include rad in your units where appropriate. (a) What is the amplitude, Ymi? (b) What is the wavelength? 10 cImI c) What is the wavenumber, k? 62 831 radm (d) What is the angular frequency, w? 4.861988631 x (e) What is the frequency, f? Enter mrnter with units. (F) What is the correct choice of sign in front of w?
