Across
- 2. a kind of radiation including visible light, radio waves, gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously.
- 4. distance between the crests or between the troughs of two adjacent waves
- 6. The part of a longitudinal wave where the particles of the medium are close together.
- 7. the height of a wave's crest
- 10. The bending of a wave as it passes at an angle from one medium to another
- 11. high-energy electromagnetic wave that has a slightly shorter wavelength and higher frequency than an ultraviolet wave
- 15. electromagnetic wave that has a slightly shorter wavelength and higher frequency than visible light, and carries enough energy to cause chemical reactions
- 16. change of pitch when a sound source is moving inrelation to an observer
- 18. material in which a wave travels
- 19. low-frequency, low energy electromagnetic wave that has a wavelength between about 1 mm and 30 cm
- 22. rapid back-and-forth motion that can occur in solids,liquids, or gases
- 25. frequency, low energy electromagnetic wave that has a wavelength longer than about 30 cm
- 26. light energy hitting the surface is converted to heat energy
- 27. A disturbance that transfers energy from place to place
- 28. perception of how high or low a sound seems
- 29. a material that scatters light as it passes through
- 30. increase in amplitude that occurs when an object vibrating at its natural frequency absorbsenergy from a nearby object vibrating at the same frequency
Down
- 1. highest point of a wave
- 3. Light that is bounced off the surface of an object
- 5. high-energyelectromagnetic wave with a shorter wavelength and higher frequency than all other types of electromagnetic waves
- 8. the particles in the material that carries the wavemove back and forth along the direction that the wave travels
- 9. waves energy that travels trough space as light and other forms of radiation; don't need a medium to travel
- 12. The part of a longitudinal wave where the particles of the medium are far apart
- 13. the number of complete wavelengths that pass a point in a given time; measured in hertz
- 14. entire range of electromagnetic waves with different frequencies and wavelengths
- 17. when light passes through the material without being scattered
- 20. wave electromagnetic wave that has a wavelength shorter than a microwave but longer than visible light
- 21. a longitudinal wave that can only travel through matter
- 23. lowest point of a wave
- 24. a material that you can see clearly what is on the other side
