Question

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

Explanation:

• Compression: In a longitudinal wave, compression is the region where the particles are close together. In the spring toy model, the first label (left - most) is where the coils of the spring are closely packed, so it is compression.
• Rarefaction: Rarefaction is the region where the particles are spread apart. In the spring toy model, the middle label is where the coils of the spring are more spread out, so it is rarefaction.
• Wavelength: Wavelength is the distance between two consecutive compressions or two consecutive rarefactions. In the spring toy model, the last label (right - most) represents the distance between two similar points (e.g., from one compression to the next compression - like the length of one full cycle of compression - rarefaction - compression), so it is wavelength.

Answer:

Left - most label: compression, Middle label: rarefaction, Right - most label: wavelength.
