Question

these models show two different waves eli created in the spring toy. select the model of the wave with the greater wavelength.

Explanation:

Wavelength in longitudinal waves is the distance between consecutive compressions (or rarefactions). The lower spring model has a longer distance between its compressed regions compared to the upper one, meaning it has a greater wavelength.

Answer:

The lower spring toy model (the second image with the spring that has more extended rarefaction regions between compressions)
