Across
- 1. the distance between two corresponding points on adjacent waves, such as two crests or two troughs
- 5. speed the rate at which a wave propagates through a medium, and it's calculated as the product of its frequency and wavelength
- 8. the material or substance through which a wave or energy propagates
- 9. the bending of light (or other waves) as it passes from one transparent substance to another
- 12. happens when two waves overlap in such a way that they combine to create a larger wave
- 13. the range of all electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays, organized by their wavelengths and frequencies
- 14. the spreading out of waves as they pass through an aperture or around objects
- 15. the change in frequency of a wave (like sound or light) perceived by an observer when the source of the wave and the observer are moving relative to each other
Down
- 2. waves in which the direction of propagation aligns with the direction of vibration of the medium
- 3. a wave that oscillates perpendicularly to the direction of the wave's advance
- 4. the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated
- 6. occurs when waves come together so that they completely cancel each other out
- 7. the transmission of energy through oscillating electric and magnetic fields at the speed of light
- 10. the number of occurrences of a repeating event per unit of time
- 11. the maximum displacement or distance moved by a point on a vibrating body or wave, measured from its equilibrium position
