1 answer:
8. Energy travels in what direction?
9. Draw how the amplitude is measured.
8. This type of wave is known as a longitudinal wave , so named because the energy travels along the direction of vibration of the particles.
9. Amplitude is generally calculated by looking on a graph of a wave and measuring the height of the wave from the resting position. The amplitude is a measure of the strength or intensity of the wave. For example, when looking at a sound wave, the amplitude will measure the loudness of the sound.
