Across
- 3. Number of wave cycles per second measured in hertz (higher frequency means higher pitch sound or more energy)
- 6. WAVES Waves that can travel through empty space and do not need a medium (like light from the sun or radio signals)
- 8. A disturbance that transfers energy through a medium without permanently moving the medium itself (like a ripple on a pond)
- 9. Lowest point of a wave (like the bottom of an ocean wave)
- 10. Half the height of a wave from its resting position to peak (taller amplitude means louder sound or brighter light)
- 12. Material that carries a wave; only mechanical waves need one (like water for ocean waves or air for sound)
Down
- 1. WAVE Wave where particles vibrate parallel to the direction the wave travels (like a sound wave pushing air molecules)
- 2. Distance between two consecutive crests or troughs (shorter wavelength means higher pitch sound or bluer light)
- 4. Highest point of a wave (like the top of an ocean wave)
- 5. WAVE Wave where particles vibrate perpendicular to the direction the wave travels (like a wave on a string or visible light)
- 7. WAVES Waves that require a medium and cannot travel through empty space (like sound or water waves)
- 11. Time for one complete wave cycle (like the time between two ocean wave peaks)
