Physical Science Vocabulary
Explore the essential vocabulary of sound waves in physical science. This guide covers critical terms such as sound, vibrations, frequency, pitch, wavelength, cochlea, longitudinal waves, echo, compression, and rarefaction. Gain insight into how sound is transmitted through vibrating objects, the nature of wave vibrations, and how pitch and frequency are related. Learn about the structure of the ear and the mechanisms behind echo and wave propagation. This comprehensive overview will enhance your understanding of sound within the physical science framework.

Physical Science Vocabulary Week23
1) sound • Waves that transmit disturbances produced by vibrating objects
2) vibrations • Rapid, back-and-forth movements of particles
3) frequency • Number of wavelengths that pass a given point in one second; measured in hertz (Hz).
4) pitch • The highness or lowness of a sound
5) wavelength • The distance between two successive and comparable points on a wave
6) cochlea • A spiraled, hollow chamber of bone within the ear
7) Longitudinal wave • A wave in which particles vibrate back and forth along the same path that the wave travels (compressional wave)
8) echo • A reflected sound wave.
9) compression • Part of the longitudinal wave where the particles bunch up closer together
10) rarefaction • Part of a longitudinal wave in which the particles expand and move apart
