- 5. The bouncing back of a wave when it hits a surface through which it cannot pass.
- 7. A wave that can travel through a vacuum without a medium, such as light waves.
- 8. Electromagnetic radiation of high energy and very short wavelength, which is able to pass through many materials opaque to light.
- 9. A wave that requires a medium (solid, liquid, gas) to travel through, such as sound waves.
- 10. The distance between two consecutive points of a wave that are in a phase, such as crest to crest or trough to trough.
- 11. A type of wave where the medium moves parallel to the direction of the wave.
- 13. The speed at which a wave travels through a medium, typically calculated as the wavelength multiplied by the frequency.
- 14. The highest point of a wave.
- 15. The lowest point of a wave.
- 16. Electromagnetic radiation with wavelengths longer than visible light but shorter than microwaves.
- 19. A particle representing a quantum of light or other electromagnetic radiation.
Down
- 1. The range of all types of electromagnetic radiation from radio waves to gamma rays, arranged in order of their wavelengths or frequencies.
- 2. Electromagnetic radiation with a wavelength shorter than that of visible light but longer than X-rays.
- 3. The bending of waves around obstacles and the spreading out of waves as they pass through openings.
- 4. The number of complete waves that pass a certain point in a given amount of time, typically measured in hertz (Hz).
- 6. A type of wave where the medium moves perpendicular to the direction of the wave.
- 12. The combination of two or more waves that results in a new wave pattern.
- 17. The bending of a wave as it passes from one medium to another medium.
- 18. The maximum distance a wave moves from its rest position. It indicates the energy carried by the wave.
