Just a quick question-- can compressions and rarefractions be compared to nodes and antinodes in calculations? For example, I have calculated the wavelength of a given longitudinal traveling wave and I am supposed to find the distance from one compression to an adjacent compression. I calculated this the same as you would from node to node where the distance between each is half a wave. However, when I tried this theory, (assuming that the distance between a compression and another compression is half a wave) it ended up being wrong. Please help soon-- I am reviewing for a Physics final tomorrow and came across this problem. I hope you can help clear it up. Thanks(adsbygoogle = window.adsbygoogle || []).push({});
