Which property of waves is the distance between one point on a wave and that same point on the wave next to it? a. wavelengthb. speedc. frequencyd. amplitude wavelength

The correct answer is "wavelength". In fact, the wavelength of a wave is defined as the distance between two consecutive corresponding points of the wave: for instance, the distance between two consecutive crests, or the distance between two consecutive throughs.

Alinear relationship would look like a straight line on the graph. it could have a positive negative or 0 slope. so it could be a line potentially going in any direction but it must be perfectly straight.
