Sound Wave Crossword Puzzle

QUESTIONS LIST:

• vibration: a movement about a fixed point described as a to-and-fro or backward-and-forward motion.
• sound wave: a wave created when an object vibrates and causes particles in a medium to vibrate too.
• air: the gas where sound waves travel by vibrating particles.
• liquid: a state of matter where particles are closer than in gases but can move around one another, allowing sound to travel faster.
• solid: a state of matter where particles are tightly packed, allowing sound to travel fastest due to strong particle interactions.
• voice box: a structure in the neck containing vocal cords that vibrate to produce sound.
• vocal cords: the part of the voice box that vibrates when you talk or sing.
• rarefaction: a region where air particles spread out as the vibrating object moves away.
• compression: a region where air particles are squashed together when the vibrating object moves toward them.
• vacuum: a space with no particles where sound waves cannot travel.
• bell jar: a container used in experiments to demonstrate that sound cannot travel through a vacuum.
• echo: the sound heard when a sound wave is reflected back and reaches the ear after more than 0.1 seconds.
• acoustic panels: soft materials used in studios to absorb reflected sound and prevent echoes.
• elastic band: a material that vibrates easily to demonstrate sound production.
• guitar string: a string that vibrates to create sound waves and musical notes.
• tuning fork: a tool used to create a pure tone by vibrating.
• long spring: a model used to demonstrate the movement of particles in compression and rarefaction.
• song: a series of sounds emitted by humpback whales to communicate over long distances.
• ultrasound: high-frequency sound waves beyond human hearing, used by animals like bats and dolphins.
• sonar: a system that uses sound waves to detect objects underwater by reflecting them.
