(a) Sketch graphs of y versus x for the function
y(x, t) = (0.80 mm) sin (kx − (t)
For the times t = 0, 0.96 s, and 1.92 s. Make all three graphs of the same axes, using a solid line for the first, a dashed line for the second, and a dotted line for the third. Use the values k = (/(5.0 cm) and w = ( ( / 6.0) rad/s.
(b) Repeat part (a) for the function
y( x, t ) = (0.50 mm) sin ( kx + (t )
(c) Which function represents a wave traveling in the -xdirection and which represents a wave traveling in the + x-direction?
