Mechanical Waves And Sound

Subject : engineering
Instructions:
  • Answer 35 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A disturbance in matter that carries energy from one place to another






2. A technique used for determining the distance to an object underwater






3. The frequency of a sound as you perceive it






4. A change in sound frequency caused by motion of the sound source - motion of the listener - or both






5. When a wave bounces off a surface that it cannot pass through






6. A wave that appears to stay in one place - it does not seem to move through the medium






7. When two or more waves overlap or combine together






8. A wave that travels along a surface separating two media (more than one medium)






9. The response of a standing wave to another wave of the same frequency






10. The bending of a wave as it moves around an obstacle or passes through a narrow opening






11. Wavelength x frequency






12. A unit that compares the intensity of different sounds






13. The distance between a point on one wave and the same point on the next cycle of the wave






14. An area where the particles in a medium are spaced close together






15. A physical response to the intensity of sound - modified by physical factors






16. A wave that causes the medium to vibrate at right angles to the direction in which the wave travels






17. The time required for one cycle - a complete motion that returns to its starting point






18. A wave in which the vibration of the medium is parallel to the direction the wave travels






19. The bending of a wave as it enters a new medium at an angle






20. The number of complete cycles in a given time






21. Longitudinal waves - compressions and rarefactions that travel through a medium






22. The material through which a wave travels through






23. The lowest point below the rest position






24. Any motion that repeats at regular time intervals






25. A point on a standing wave that has no displacement from the rest position






26. Is the maximum displacement of the medium from its rest position on a wave






27. Consists of the cochlea and the auditory nerve






28. A point where a crest or trough occurs midway between two nodes






29. When two or more waves combine to produce a wave with a smaller displacement






30. An area where the particles in a medium are spread out






31. The rate at which a wave's energy flows through a given area






32. When two or more waves combine to produce a wave with a larger displacement






33. Consists of the eardrum - hammer - anvil - & stirrup






34. The highest point of the wave above the rest position






35. Consists of the ear canal
