(Figure 1) (a) is a snapshot graph at t = 0s of two waves approaching each other at 1.0 m/s .

Part A: At what time was the snapshot graph (b) taken?

Then, we’ll identify the solution, or find information related to this equation by studying the graph.

Wave peaks can travel up to 1 m.

Time t=(1/1) seconds

t=1sMany thanks

Please rate

The correct answer is t=2s, not 1s
