eps would I take to better understand how D(x,t) = f(x - v t) + g(x + v t) could be a solution to the general wave equatio

Snapshot: This a snapshot at t = 2s of the wave function: Calculate or read from the graph: y(x,t) = Axsin 2 × sin [2x (1-1)] a) Amplitude A, the wavelength A and the wave number k. b) Determine all possible periods T consis- tent with the graph. For the largest pe- riod T calculate the speed of the propaga- tion v. In which direction does the wave propagate (in +x or -x)? c) What is the maximal speed and accelera- tion of the points along the wave? y(m) 2 1 1 2 3 4 x(m)

please answer the questions based on the wave equation: v=fλ   a) What is the independent parameter? b) What is the dependent parameter? c) What parameter will you plot on your y-axis? d) If you perform a line of best fit, what will be your slope? e) How will get g from your line of best fit? What's the equation for g? f) What is the equation for the uncertainty in g? g) write a procedure for experimenting to measure g

7. 8. 9. PQ represents the boundary between regions I and II, having different depths, in a ripple tank containing water. Wave fronts are shown crossing the boundary. (a) (b) (c) (d) (e) I NOTE: v represents wave velocity A represents wavelength f represents frequency T represents period II (a) (b) (c) (d) (e) Which of the following correctly describes the waves in region II as compared to those in region I? In region II, f is the same, v is less, and A is less than in region I. In region II, f is the same, v is greater, and A is greater than in region 1. In region II, f is the same, v is greater. and A is less than in region I. In region II, v is the same, T is less, and A is less than in region I. In region II, v is the same, T is greater, and A is less than in region I. When two point sources placed a fixed distance apart vibrate in phase, nodal lines are produced. Which one of the following statements concerning these lines is incorrect? Energy is transmitted away from the sources…
