  1. Physical Science Vocabulary Week22

  2. 1) amplitude • For a transverse wave, one half the distance between a crest and a trough

  3. 2) wavelength • For a transverse wave, the distance between the tops of two adjacent crests or the bottoms of two adjacent troughs; for a compressional wave, the distance from the centers of adjacent rarefaction or adjacent compressions.

  4. 3) frequency • Number of wavelengths that pass a given point in one second; measured in hertz (Hz).

  5. 4) reflection • Occurs when a wave strikes an object or surface and bounces off.

  6. 5) refraction • Bending of a wave as it moves from one medium into another medium.

  7. 6) diffraction • Bending of waves around a barrier.

  8. 7) interference • Occurs when two or more waves combine and form a new wave when they overlap.

  9. 8) echo • A reflected sound wave.

  10. 9) period • Refers to the amount of time it takes for a wave to complete one full cycle.

  11. 10) Wave speed • The speed at which a wave travels.
