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






2. Any motion that repeats at regular time intervals






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






4. The material through which a wave travels through






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






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






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






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






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






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






11. A disturbance in matter that carries energy from one place to another






12. Consists of the cochlea and the auditory nerve






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






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






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






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






17. The frequency of a sound as you perceive it






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






19. The lowest point below the rest position






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






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






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






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






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






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






26. Consists of the ear canal






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






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






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






30. Wavelength x frequency






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






32. When two or more waves overlap or combine together






33. The number of complete cycles in a given time






34. A unit that compares the intensity of different sounds






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