Ch. 9: Waves

5. A wave in which the particles in the medium move back and forth along the same direction that the wave travels
6. The less dense region of a longitudinal wave
7. The number of wavelengths that pass a fixed point each second
9. The high points of a transverse wave
11. The more dense region of a longitudinal wave
12. The distance between one point on a wave and the nearest point just like it
13. A measure of the size of the disturbance from a wave
15. The bending of a wave caused by a change in its speed as it travels from one medium to another

1. Waves that can travel only through matter, such as sound waves
2. The process of two or more waves overlapping and combining to form a new wave
3. A wave in which the particles in the medium move back and forth at right angles to the direction that the wave travels
4. A repeating disturbance that transfers energy through matter or space
8. The bending of a wave around an object
10. The low points of a transverse wave
14. Matter through which a wave travels
