Physical Science

3. The time required for one to complete vibration of a particle in a medium-or of one rise and fall of a swimmer in the ocean.
6. interference 3 cm + 4 cm of displacement.
9. Waves Consists of changing electric and magnetic fields in space.
10. Simply the bouncing back of a wave when it meets a surface or boundary.
11. The greatest distance that particles are displaced from their normal resting positions.
12. waves Waves that cause the particles in a medium to vibrate parallel to the direction of the wave motion.
13. Wave Results from interference between a wave and its reflected wave.
15. Interference When the crest of one wave meets the crest of another wave the resulting wave has a smaller amplitude.
16. A pattern when waves pass through each other.
18. The high points of a transverse wave.
19. Effect This change in the observed frequency of a wave.

1. The number of wavelengths that pass a point in a given time time interval.
2. The bending of waves as they pass an edge.
4. The distance from one crest to the next crest or from one trough to the next trough.
5. Waves Waves that require a medium.
7. The low points of a transverse wave.
8. The bending of waves when they pass from one medium to another.
14. The matter through which a wave travels.
17. Waves Waves in which the motion of the particles is perpendicular to the motion of the wave.
