Across
  1. 5. the distance from one point of the wave to the equivalent point on the next wave
  2. 6. the maximum displacement that the wave reaches from its equilibrium position
  3. 10. ray used for medical imaging, can penetrate skin but not bone
  4. 11. a wave in which the oscillations are parallel to the direction of travel
  5. 13. third from the end on the electromagnet scale, with relatively low frequency, long wavelength
  6. 14. the highest point of the wave
Down
  1. 1. third from the end, closest to gamma rays, used in sun beds
  2. 2. ray used in the treatment of cancer
  3. 3. used in satellite communications and cooking food
  4. 4. the number of waves passing a fixed point per second, measured in hertz
  5. 7. the change in direction of a wave passing from one medium to another, typically seen with light
  6. 8. a wave in which the oscillations are perpendicular to the direction of travel
  7. 9. ray used for television, radio and bluetooth
  8. 12. the lowest point of the wave
