In the diagram below, what is the property of the wave indicated by the letter A? Diagram of wave. The distance between the highest points of consecutive waves is labeled A. Amplitude Frequency Trough Wavelength Question 6(Multiple Choice Worth 2 points) Which of the following best describes why longitudinal waves cannot travel in space? Longitudinal waves can travel without a medium. Gravity interferes with the travel of longitudinal waves in space. There are too few air particles in space for longitudinal waves to travel. Space contains too many particles that interfere with the travel of longitudinal waves. Question 7(Multiple Choice Worth 2 points) Which of the following represents the wavelength of a wave? Diagram of a wave. The point between the highest and lowest points is labeled A; the height is labeled B; the highest point is labeled C; the distance between the highest points of consecutive waves is labeled D.
