Instructions: Read the passage discussing waves with varying wavelengths, frequencies, and amplitudes.
A student is curious about the reasons behind the differences in volume and pitch among sounds. To explore this, he embarks on research to uncover the wave properties responsible for these variations.
Initially, he grasps that a wave constitutes a recurring pattern characterized by specific wavelength, frequency, and amplitude. The amplitude of a wave represents the maximum distance above or below the equilibrium point. The energy of a wave is determined by squaring its amplitude. Frequency denotes how often the wave pattern repeats, and the energy transferred by the wave is proportional to its frequency. For instance, in sound waves, the amplitude correlates with loudness, while frequency correlates with pitch.
During his investigation, the student encounters graphs that aid his comprehension of how wave properties influence their energy.
Graph 1 depicts the amplitudes (measured in meters) of three waves (labeled wave 1, 2, and 3) as they travel through a medium over time (measured in seconds).
Graph 2 displays an alternative set of three waves (labeled as wave X, Y, and Z) traversing through a medium.
