Across
- 3. The reduction of density and pressure in a medium-such as air to water- as a longitudinal wave (like sound) travels through it.
- 8. When two or more waves travel through the same medium simultaneously, they pass through each other without being disturbed.
- 11. The periodic, back-and-forth, or up-and-down motion of an object or particle around a central equilibrium position.
- 14. Phenomenon in physics where two or more waves overlap, with the crest of one wave aligning with the trough of another, resulting in a new wave with a smaller, or zero amplitude.
- 16. A point on a standing wave where constructive interference causes maximum amplitude as oscillation, with the medium moving between high and low displacement.
- 17. The change in frequency or pitch of a wave (sound or light) perceived by an observer when the wave source and the observer are moving relative to each other.
- 18. A logarithmic unit used in physics to measure the intensity of sound, power, or signal strength relative to a reference level.
- 21. The inherent rate in which an object or system tends to oscillate, vibrate, or resonate when disturbed, without any driving or damping force acting up on it.
Down
- 1. Flight through an atmosphere at speeds exceeding Mach 5, or five times the speed of sound.
- 2. A sinusoidal wave (or oscillation) with a frequency that is a positive integer multiple (2x,3x, ect.) of a fundamental, lowest-resonant frequency.
- 4. A phenomenon where two or more waves of the same frequency and phase superimpose, aligning their crests and troughs to create a new wave with a larger amplitude.
- 5. The subjective perception of sound frequency, determining how high or low a tone sounds to a listener.
- 6. Wave pattern formed by the interference of two traveling waves with the same frequency and amplitude moving in opposite directions.
- 7. The reduction in volume or size of a material caused by applying inward-pushing forces (stress), which brings parties or molecules closer together.
- 9. Relating to or denoting sound waves with a frequency below the lower limit of human audibility.
- 10. The phenomenon where two or more waves superpose (overlap) to form a resultant wave of greater, lower, or the same amplitude.
- 12. The periodic, rhythmic functions in loudness (intensity) heard when two sound waves of slightly different frequencies interfere with each other
- 13. A physics phenomenon where an oscillating system experiences a dramatic increase in amplitude when driven by an external force that matches its natural frequency.
- 15. A point along a standing wave where the wave has minimum amplitude, typically zero displacement.
- 19. longitudinal waves that are characterized by high-frequency, short wavelength oscillations that can be focused, reflected, and absorbed.
- 20. A dimensionless quantity in physics representing the ratio of an object's speed (v) to the local speed of sound (c) in a given medium (usually air)
