Two traveling waves g(x,t) = Asin(kx-wt) and h(x,t) = Asin(kx+wt+phi)

Click For Summary
The discussion revolves around identifying nodes in the superposition of two traveling waves, g(x,t) = Asin(kx-wt) and h(x,t) = Asin(kx+wt+phi). Participants note that the provided figure does not display nodes or antinodes because it does not plot the combined function g+h. To determine the locations of nodes, one must find points where g+h equals zero. The conversation suggests that the original question may be part of a multiple-choice format, prompting further clarification on the question and possible answers. Understanding the conditions for nodes is crucial for solving the problem effectively.

Where in the figure are there nodes at t1?
Please post your working.
 
Hi haruspex, thank you for yr time to have a look at my question. the Figure doesn’t include nodes/anti nodes.

That's only because the figure doesn't plot g+h. You can easily see where the nodes must be.

You seem to have completely misunderstood the question.
You have to find a place where g+h is always zero.
 
The "statement" of the problem looks like one of the possible answers to a multiple choice question. If that is true, what is the question and what are the other choices?

If have close pipe system with water inside pressurized at P1= 200 000Pa absolute, density 1000kg/m3, wider pipe diameter=2cm, contraction pipe diameter=1.49cm, that is contraction area ratio A1/A2=1.8 a) If water is stationary(pump OFF) and if I drill a hole anywhere at pipe, water will leak out, because pressure(200kPa) inside is higher than atmospheric pressure (101 325Pa). b)If I turn on pump and water start flowing with with v1=10m/s in A1 wider section, from Bernoulli equation I...
