Hi thank you for your time to read my inquiry. The question was (need to refer to the attached image file), a) Examine the graphs. Is the wave transverse, torsional, or longitudinal? Justify your answer. b) What are two indications that the wave could be a sound wave? I can distinguish between the transverse, torsional and longitudinal waves, when they are expressed in animation, however when they are expressed in sin graph, I get stuck in the problem. For the fact that all 3 types of waves can be expressed into sin graph what are some things that I should know when looking at the graph before comparing them? Any tip would be appreciated. Thank You!
