2. A) For a transverse wave described by the equation y(x,t) = 5m sin((2m-1)x + (4 rad/s)t), draw a graph of y vs. x for this wave at t = 37/2 (T is the period). Be sure to label the axes so that the amplitude and wavelength are clear. y 2 m- B) The sinusoidal wave graphed at right moves to the right with a speed of 5m/s. Write an equation y(x,t) that describes this wave [the only unspecified quantities in the function should be the variables]. Is t = 0 C) For the sinusoidal wave graphed at two different times at right, 05m the maxima marked with a dot moves to the left. Write an equation y(x, t) that describes it [the only unspecified quantities in the function should be the variables). 1=2s 3m
