Final Answer:
4a. Transverse wave
4b. One full cycle (peak to next peak, or trough to next trough) — mark the horizontal distance between two consecutive peaks
4c. Vertical distance from the middle line (rest position) to a peak (or to a trough) — mark that height
4d. Light waves, radio waves, waves on a string
5a. Longitudinal wave
5b. Distance between two consecutive compressions (or two consecutive rarefactions) — mark that horizontal span
5c. Sound waves in air, ultrasound, seismic P-waves
6a. Light travels much faster than sound.
6b. The second sound comes from lightning farther away, so the sound takes longer to reach him.
6c. Sound gets weaker (spreads out and loses energy) over longer distances, so the farther lightning produces a quieter sound.
