ACROSS 5. Integral multiples of the fundemental frequency 8. The condition that exists when the frequency of a force applied to a system matches the natural frequency of vibration of the system 10. The interference that results when individual displacements on opposite sides of the equilibrium position are added together to form the resultant wave 12. The interference that results when individual displacements on the same side of the equilibrium position are added together to form the resultant wave 13. This type of wave is a repeating disturbance 14. The maximum negative displacment of a transverse wave 15. A place of maximum constructive interference on a standing wave 19. The points that remain stationary in standing wave interference 22. A single nonperiodic disturbance 24. A measurment of relative sound intensity 25. The region of a longitudinal wave in which the density and pressure are greater than normal 27. The combination of two overlapping waves 28. The number of cycles or vibrations per unit of time 29. The lowest possible frequency of a standing wave |
DOWN 1. These waves are produced by periodic waves of the same frequency, amplitude, and wavelength traveling in opposite directions 2. These are formed by the interference of two waves of slightly different frequencies traveling in the same direction 3. The quality of a steady musical sound that is the result of a mixture of harmonics present at different intensities 4. How high or low we perceive a sound to be, depending on the frequency of the sound wave 6. The region of a longitudinal wave in which the density and pressure are less than normal 7. The amount of maximum displacement on a wave 9. The distance from one part of a wave to the same part of the next wave 11. A ___ pipe can produce all harmonics 12. A ___ pipe can produce only even-numbered harmonics 16. This effect casues a change in the frequency of a wave due to motion 17. The rate of energy flow through an area 18. How waves interact as they pass through each other 20. Type of wave where the motion of the particles is parallel to the wave motion 21. The material through which a mechanical wave travels 23. Type of wave where the motion of the particles is perpendicular to the wave motion 25. The maximum positive displacement of a transverse wave 26. The time it takes to complete a cycle of motion |
