2. The world around us is filled with sound. There are loud sounds and soft sounds. There are pleasant sounds and unpleasant sounds. At this very moment, you are surrounded by sound. Where does sound come from? How does it get to your ears? Why are there different kinds of sound? The study of these questions about sound is called acoustics. Imagine a cymbal hit with a drumstick. The cymbal shakes rapidly, and this vibration causes the tiny particles in the air around it to vibrate. These vibrating air particles, called molecules, bump into the air particles next to them and make them vibrate. This spreading vibration moves outward in every direction from the cymbal in waves. When a small object is made to vibrate, the sound waves move up and down very quickly. This produces a high-pitched sound, like a high note in a song. When a large object is made to vibrate, the sound waves move up and down more slowly. This produces a low-pitched sound, like a low note in a song. Hitting a small cymbal makes a more high-pitched sound than hitting a large cymbal. a. Write the context clues that give a hint to the meaning of each of acoustics word! b. Write the context clues that give a hint to the meaning of each of vibration word! C. Write the context clues that give a hint to the meaning of each of high- pitched word!

Answer:
a. Context clues for the meaning of "acoustics":
- "The study of these questions about sound is called acoustics." In this sentence, the phrase "The study of these questions about sound" provides context that suggests "acoustics" refers to the study of sound.
b. Context clues for the meaning of "vibration":
- "The cymbal shakes rapidly, and this vibration causes the tiny particles in the air around it to vibrate." In this sentence, the word "vibration" is used in the context of the cymbal's movement and the air particles vibrating, indicating that it refers to a back-and-forth or oscillating motion.
c. Context clues for the meaning of "high-pitched":
- "When a small object is made to vibrate, the sound waves move up and down very quickly. This produces a high-pitched sound, like a high note in a song." In this sentence, the phrase "sound waves move up and down very quickly" and the comparison to "a high note in a song" provide context that suggests "high-pitched" refers to a sound with a high frequency or tone.
