Sound Waves – Loudness, Amplitude, Oscilloscopes, Pitch & Frequency

PART 1: What Is a Wave Model? 1. A wave is a pattern that ________________________ over and over again. 2. Waves are used to ________________________ real-world phenomena like sound and water waves. 3. A wave moves through a ________________________, which is the material the wave travels through. PART 2: Parts of a Wave 4. The resting position is the place where the wave would be if it were not moving. 5. The crest is the ________________________ point of a wave. 6. The trough is the ________________________ point of a wave. PART 3: Important Wave Characteristics 7. Frequency is how many times a wave ________________________ in a certain amount of time. 8. Frequency is often measured in ________________________ (waves per second). 9. For sound waves, frequency affects ________________________. 10. Amplitude is the maximum distance the wave moves from the ________________________ position. 11. A wave with a larger amplitude has ________________________ energy. 12. For sound waves, amplitude affects ________________________. 13. Wavelength is the ________________________ between repeating parts of a wave. 14. An example of wavelength is the distance from one ________________________ to the next. PART 4: Mathematical Modeling of Waves 15. Scientists use ________________________ models to connect wave characteristics to physical observations. 16. Frequency corresponds to sound ________________________. 17. Amplitude corresponds to sound ________________________. PART 5: Energy and Waves 18. Waves carry ________________________ energy, which is the energy of motion. 19. The energy of a wave depends on its ________________________ and ________________________. 20. Wave energy is proportional to the ________________________ of the amplitude. 21. If the amplitude doubles, the energy becomes ________________________ times greater. 22. The amount of energy transferred by waves in a given time is proportional to ________________________. 23. If twice as many waves pass in the same time, ________________________ as much energy is transferred. PART 6: Predicting Changes in Waves 24. If the amplitude increases, the energy of the wave will ________________________. 25. If the frequency increases, the amount of energy transferred will ________________________.
