  1. 2. Waves-motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance,
  2. 6. The rate of change of position of an object in any direction,
  3. 7. waves travel more slowly through Earth's material at the planet's surface and are predominantly lower frequency than body waves,
  4. 9. -allows a lot of light to pass through
  5. 10. planetary probes and their instruments that use radio to gain information about the target.
  6. 11. change in direction of a wave passing from one medium to another caused by its change in speed.
  7. 12. three-dimensional solid object in which the two ends are identical.
  8. 14. Waves-a disturbance or vibration in matter,
  9. 15. change in the direction of propagation of a wave that strikes the boundary between different mediums.
  10. 16. Waves- a wave in which the medium's vibration is parallel to the direction of the wave, and the medium's displacement is in the same direction as that of the wave movement,
  11. 19. region of the electromagnetic radiation spectrum where wavelengths range from about 700 nanometers (nm) to 1 millimeter (mm).
  12. 20. a point on a wave with the maximum value of upward displacement within a cycle,
  13. 22. measurement of the number of times that a repeated event occurs per unit of time,
  14. 23. radiations with a frequency ranging between 300 MHz to 300 GHz.
  15. 24. maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position,

  1. 1. electromagnetic radiation with wavelengths between 380 and 750 nm which is visible to the human eye.
  2. 3. waves form radiation that travels through the universe,
  3. 4. the lowest part,
  4. 5. row of chemical elements.
  5. 8. disturbance- that moves energy from one place to another,
  6. 9. which allow complete transmission of light,
  7. 13. distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire,
  8. 17. Rays- a form of electromagnetic radiation (EMR).
  9. 18. form of electromagnetic radiation with wavelength shorter than that of visible light, but longer than X-rays.
  10. 21. no light is able to pass through them.
