What is the difference between a conductor and an insulator
One of the differences between a conductor and insulator are the types of material. One of the major difference between the conductor and insulator is that the conductor allows the energy (i.e., current or heat ) to pass through it, whereas the insulator does not allow the energy to pass through it.

How can you tell if a sound is low pitch or high pitch?
Since pitch is such a close proxy for frequency, it is almost entirely determined by how quickly the sound wave is making the air vibrate and has almost nothing to do with the intensity, or amplitude, of the wave. That is, "high" pitch means very rapid oscillation, and "low" pitch corresponds to slower oscillation.
