Across
  1. 2. an electromagnetic wave having a wavelength between 1 millimeter and 30,000 meters, or a frequency between 10 kilohertz and 300,000 megahertz.
  2. 4. Water waves are surface waves, a mixture of longitudinal and transverse waves.
  3. 5. seismic wave, vibration generated by an earthquake, explosion, or similar energetic source and propagated within the Earth or along its surface.
  4. 9. X-rays are a form of electromagnetic radiation, similar to visible light,Unlike light, however, x-rays have higher energy and can pass through most objects, including the body.
  5. 12. the number of waves that pass a fixed point in unit time
  6. 13. a wave vibrating in the direction of propagation.
  7. 14. the time that it takes to do something
  8. 15. a decrease in the density of something. “a sound wave causes periodic rarefactions in its medium”
  9. 16. Gamma photons are the most energetic photons in the electromagnetic spectrum.
  10. 19. a disturbance that travels through a medium, transporting energy from one location (its source) to another location without transporting matter
  11. 21. a region of the electromagnetic radiation spectrum where wavelengths range from about 700 nanometers (nm) to 1 millimeter (mm).
Down
  1. 1. a longitudinal wave (such as a sound wave) propagated by the elastic compression of the medium
  2. 3. is the pattern of disturbance caused by the movement of energy traveling through a medium
  3. 6. Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated
  4. 7. waves that are created as a result of vibrations between an electric field and a magnetic field
  5. 8. the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
  6. 10. the point on the medium that exhibits the maximum amount of negative or downward displacement from the rest position.
  7. 11. (UV) radiation is defined as that portion of the electromagnetic spectrum between x rays and visible light
  8. 17. Microwave is a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter corresponding to frequencies between 300 MHz and 300 GHz respectively
  9. 18. the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position
  10. 20. the point on the medium that exhibits the maximum amount of positive or upward displacement from the rest position.
