As we tackle this multiple-dropdowns question about the wave diagram, I’ll walk through each choice in turn to clarify what the X and Y markers indicate and how the two waves compare. First dropdown consideration: What do the X and Y marks correspond to on a standard wave graph? - The X-axis on a typical wave diagram represents distance or position along the medium, which is how we define wavelength—the distance between successive crests (or troughs). This means the label for the X-mark should be Wavelength. If you instead chose Amplitude, you’d be mislabeling the horizontal spacing as a measure of vertical height, which is incorrect. - The ......Login to view full explanation
