Across
- 6. the height of a wave; the larger the amplitude the louder the sound
- 9. A wave that requires a medium through which to travel
- 11. a wave that is a disturbance of electric and magnetic fields; it moves outward at the speed of light
- 13. the loudness or softness of a sound, related to amplitude
- 14. the highest point of a transverse wave
- 15. A wave that the energy moves the same direction to the direction in which the wave travels.
- 17. the part of a longitudinal wave where the energy is pushed together
Down
- 1. a longitudinal wave that can travel only through matter
- 2. A wave that the energy moves opposite to the direction in which the wave travels
- 3. the material through which a wave travels
- 4. the highness or lowness of a sound
- 5. the lowest point of a transverse wave
- 7. a disturbance that transfers energy from place to place
- 8. the number of complete wavelengths that pass a point in a given time; the higher the frequency the higher the sound
- 10. the part of a longitudinal wave where the energy is spread out
- 12. The distance between the same spot on neighboring waves
- 16. the unit of frequency, equal to one cycle per second
