Across 5. The substance through which a wave can propagate. 6. A type of wave where the disturbance moves perpendicular to the direction of energy transfer. 7. The highest point of displacement on a transverse wave 13. A type of wave where the particles of the medium vibrate parallel to the direction of energy transfer. 15. The length of one complete wave cycle

Down 1. Waves produced by vibrating electric charges, consisting of vibrating electric and magnetic fields that travel together through space. 2. A disturbance that transfers energy through a medium, moving from one area to another. 3. The reduction in volume or the increase in pressure applied to a material, particle, or wave caused by opposing forces pushing inward 4. The maximum distance on a vibrating body or wave measured from its equilibrium (rest) position. 5. The transfer of energy through a medium or vacuum by way of vibrations 8. The repetitive back-and-forth motion of an object; vibrations 9. The rate at which a vibration occurs that constitutes a wave, 10. A single, non-repeating disturbance that travels through a medium transporting energy and momentum without transferring matter 11. The time interval required for one complete cycle of a repeating event, oscillation, or rotation 12. The reduction in density or pressure of a medium as particles spread apart 14. The lowest point of displacement on a transverse wave
