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.

Here are the answers to your questions:
Which of the statements below accurately describes the way light waves propagate?
Light waves travel faster in solids than in air. (This statement is correct because light travels fastest in solids.)
Wanda generates a transverse wave by securing a rope to a tree. Her teacher instructs her to modify the wave to demonstrate increased energy transfer. What action does she take?
She increases the frequency of the wave. (Increasing the frequency increases the energy transferred by the wave.)
Which option organizes the waves presented in Graph 1 in ascending order of energy?
The correct choice cannot be determined without the actual graphs. However, if the amplitudes were provided, you would choose the one with the lowest amplitude first, followed by the second lowest, and then the highest amplitude.
Which statement accurately contrasts the energies of the waves depicted in Graph 2?
The correct choice cannot be determined without the actual graphs. However, if you have the amplitudes of waves X, Y, and Z, you can compare them according to the amplitude-energy relationship.
Which statement below most accurately characterizes the relationship between wavelength and frequency?
The longer the wavelength, the lower the frequency. (This is true because wavelength and frequency are inversely related in wave physics.)
What enables a convex lens to project an image onto a screen?
The lens refracts light inward, producing a real image. (Convex lenses converge light rays to form real images.)
What step would most effectively finalize her model of a concave lens?
The student should illustrate the light entering the lens and then departing in lines that are spreading out. (This accurately represents how concave lenses diverge light rays.)
If you have the specific graphs or further details, I could provide more exact answers for those questions.
