Complete an illustration of the air particles and “slinky - coils” according to this graph. (b) Interpret. For each diagram, decide whether it illustrates the wave’s period or wavelength. Label this on each. (c) Reason. We increase the frequency of the sound the speaker makes. Explain how the three diagrams will change. 2. A dust particle floats in the air in front of a speaker.
