Given the question: Q: Why do waves travel faster through solids? Read this paragraph and choose the correct option from the provided answers: The speed of most waves depends on the medium, or the matter through which the waves are traveling. Generally, waves travel fastest through solids and slowest through gases. That's because particles are closest together in solids and farthest apart in gases. When particles are farther apart, it takes longer for the energy of the disturbance to pass from particle to particle through the medium. At the following URL, you can watch an animation showing what happens when a wave passes from one medium to another. Choices: - particles fuse together - particles range together - particles pipe together - particles closer together A:
The answer is:
particles closer together
