Across
- 2. The change in direction (bending)/speed of a wave as it passes across the boundary between two different media
- 6. The point of maximum positive displacement on a transverse wave (the highest point);the opposite is a trough
- 9. Waves that have a constant phase difference and the exact same frequency; a requirement to observe an interference pattern
- 10. A wave where the oscillation of the particles is parallel to the direction of energy propagation
- 13. The maximum displacement of a wave from its equilibrium (rest) position; an indicator of the wave's energy
- 15. waves that do not require medium to transfer energy
- 16. A region in a longitudinal wave where the particles of the medium are pulled furthest apart from each other creating low pressure
Down
- 1. waves (usually light) that consist of a single, specific wavelength or frequency
- 3. The shortest distance between two consecutive points on a wave that are completely in phase
- 4. waves that require medium to transfer energy
- 5. The spreading out of a wave as it passes through an aperture (gap)
- 7. this occurs when an oscillating system is driven by an external force acting at the system's own natural frequency resulting in an increase in the amplitude
- 8. A wave where the oscillation (displacement) of the particles/fields is perpendicular (at right angles) to the direction of energy propagation
- 11. The apparent shift in the observed frequency and wavelength of a wave, caused by the relative motion between the source of the wave and the observer
- 12. A disturbance that transfers energy and information from one place to another without the net transfer of physical matter
- 14. The principle stating that when two or more waves meet and overlap in a medium, the resultant displacement at any given point is the vector sum of the individual displacements of the waves
