Across
- 6. Wave Both the direction of the medium and the wave's motion are perpendiculars (ex. Light waves).
- 7. The highest part of a wave.
- 8. The distance between the crests of a wave (A shorter ___________________ demonstrates a higher frequency in sound waves and higher energy in light waves).
- 9. The amount of wave produced in a set time (Higher _______ also means more energy).
- 11. Interference When two waves meet and are displaced in the same direction.
- 12. When a wave (or substance) is unable to pass through a material and instead bounces back.
- 16. Effect The apparent change in the frequency of a sound caused by the motion of either the listener or the source of the sound (ex. A siren becoming louder as the car moves towards you, and quieter as the car moves away from you).
- 17. Interference When two waves meet and are displaced into opposite directions.
Down
- 1. Waves Waves produced through vibrating particles, that are almost always Transverse wave. These waves are capable of moving energy through a vacuum (Light waves).
- 2. The loudness or brightness of a wave (Greater ________ means more energy).
- 3. A wave's direction is changed when moving from one medium into another
- 4. A term to describes ways energy is transferred (ex. electromagnetic, sound, ocean, and seismic).
- 5. Waves Both the direction of the medium and the wave's motion are parallel (ex. Sound waves).
- 10. A substance through which a wave travels (ex. Solid, Liquid, Gas).
- 13. The lowest part of a wave.
- 14. When waves are bent around a barrier or through an opening.
- 15. Waves Waves can be longitudinal, transversal, or surface, and need a medium in order to move energy. Energy is transferred between particles (Sound waves).
