Across
- 3. This is the peak, or highest point, of a wave.
- 4. This is the material in which a mechanical wave travels.
- 8. A rhythmic disturbance that carries energy through matter or space.
- 9. The person or device that receives the wave or information.
- 12. This the bottom, or lowest point, of a wave.
- 14. A change in sound frequency due to the relative motion of either the source of sound or the detector.
- 15. This is the distance from the peak to a peak of a successive wave.
- 16. This is an imaginary line perpendicular to a flat, reflective surface.
- 18. This is the speed of light in vacuum divided by the speed of light in the medium. This determines the amount of bending of a light wave.
- 19. This is the angle at which light leaves or bounces off of a surface relative to the normal, or an imaginary line perpendicular to the surface. The law of reflection states that this angle is equal to the angle of incidence.
- 22. A compression wave of gas, liquid, or solid, that is detected by your ear.
- 24. This is the constructive or destructive overlap of waves.
- 27. This is the reduction in the density of a medium.
- 28. In a transverse wave, this is the magnitude of height of a wave from origin to crest.In a longitudinal wave, this is corresponds to how much the wave is compressed, as compared to areas of little compression.
- 29. This is the portion of the electromagnetic spectrum that human eyes can detect.
- 30. This is a wave whose energy travels in the same direction as the energy being transferred.
Down
- 1. The complete range of light waves organized by wavelength/frequency.
- 2. This is an interaction in which two waves meet, matching the crest of one with the trough of the other. They cancel out, producing smaller crests or troughs than a single wave alone.
- 5. A propagating wave in space with electric and magnetic components. These components oscillate at right angles to each other. It may travel in a vacuum.
- 6. This is the number of complete movements of a wave per second.
- 7. This is mechanical oscillations about an equilibrium point. The oscillations may be regular and repeating motion around a fixed position like a pendulum or they may be random.
- 10. The bouncing back of a wave from a surface.
- 11. Also called a longitudinal wave, they are waves whose direction of vibration is the same as their direction of travel.They produce compression and rarefaction when traveling through a medium.
- 13. The bending of a wave as it moves from one medium to another.
- 17. This is the angle that light strikes a surface relative to the normal, or an imaginary line perpendicular to the surface. The law of reflection states that this angle is equal to the angle of reflection.
- 20. This is a type of wave that travels in one direction, but the energy travels perpendicular to this direction.
- 21. This is a spreading out of a wave around corners or through holes.
- 23. A wave which needs a medium (solid, liquid, gas) in order to propagate itself.
- 25. This is the increase in density of a medium due to wave travel.
- 26. This is the high or low tone or frequency in which a speech is made.
