Across
- 2. is the number of waves produces per unit time
- 6. are extremely high frequency radio waves
- 8. top of the hill
- 10. the hollow muscular organ forming an air passage to the lungs and holding the vocal cords in humans and other mammals
- 11. is a longitudinal wave that is created by vibrating objects
- 13. is the part of the electromagnetic spectrum visible to the unaided eye
- 14. A wave in which medium vibrates at right angles to the direction of its propagation
- 15. bottom of the valley
- 16. is the distance traveled by a wave per unit of time
- 18. the attribute of a sound that determines the magnitude of the auditory sensation produced

Down
- 1. one of the waves that are propagated by simultaneous periodic variations of electric and magnetic field intensity
- 3. characteristic which enables us to distinguish one sound from another
- 4. is being transported in waves

- 6. Energy transfers through a medium
- 7. the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position
- 9. is a region in a longitudinal wave where the particles are closest together.
- 12. is the time taken for one complete cycle of the wave to pass a reference point
- 17. is the distance between any two successive points in a wave that are in phase with each other
- 19. the highness or lowness of a tone
