@surjithayer Thank you for the visual! I think it is C and A

anonymous · Answer

Does that seem like one wavelength?

tkhunny · Answer

C is on the axis
A is a peak
That is NOT the wave length

Pick Axis-to-Axis, Peak-to-Peak, or Trough-to-Trough.  Don't mix them up.

anonymous · Answer

distance between two consecutive crests or consecutive troughs or the one wave as i have shown.
