1 WEEK21 PHYSICAL SCIENCE VOCABULARY

2 1) WAVE Any disturbance that transfers energy through matter or space

3 2) MEDIUM Material through which waves can travel

4 3) MECHANICAL WAVE A wave that needs a medium in which to travel

5 4) TRANSVERSE WAVE A wave the transfers energy in a direction that is perpendicular (at a right angle) to its medium

6 5) LONGITUDINAL WAVE A wave in which particles vibrate back and forth along the same path that the wave travels

7 6) COMPRESSION Part of the longitudinal wave where the particles bunch up closer together

8 7) RAREFACTION Part of a longitudinal wave in which the particles expand and move apart

9 8) ELECTROMAGNETIC WAVE Disturbance that transfers energy through a field

10 9) CREST The highest point of a transverse wave

11 10) TROUGH The lowest point of a transverse wave
