Question

this model shows the longitudinal wave in the spring toy. label the model. rarefaction compression wavelength

Explanation:

• Compression: In a longitudinal wave, compression is the region where the particles are closest together. In the spring - toy model, the first label (the left - hand side label) corresponds to compression as it shows the tightly - packed part of the spring.
• Wavelength: Wavelength in a longitudinal wave is the distance between two consecutive compressions or two consecutive rarefactions. The bottom label in the spring - toy model represents the wavelength as it measures the length over which the wave pattern repeats.
• Rarefaction: Rarefaction is the region in a longitudinal wave where the particles are farthest apart. The right - hand side label in the spring - toy model is for rarefaction as it shows the part of the spring where the coils are more spread out.

Answer:

Left - hand side label: compression, Right - hand side label: rarefaction, Bottom label: wavelength.
