Across
  1. 6. the spreading of waves around obstacles
  2. 7. effect-the effect produced by a moving source of waves in which there is an apparent upward shift in frequency for observers
  3. 8. the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
  4. 10. The maximum extent of a vibration or oscillation, measured from the equilibrium
  5. 11. the substance that transfers the energy, or light from one substance to another substance or from one place to another, or from one surface to another.
  6. 12. abrupt change in the direction of propagation of a wave that strikes the boundary between different mediums.
  7. 13. interference- the interference of two waves of equal frequency and opposite phase
Down
  1. 1. spectrum- The range of wavelengths over which electromagnetic radiation extends.
  2. 2. wave- wave consisting of a periodic disturbance or vibration that takes place in the same direction as the advance of the wave.
  3. 3. wave-a wave vibrating at right angles to the direction of its propagation.
  4. 4. interference-the interference of two or more waves of equal frequency and phase,
  5. 5. the change in direction of a wave passing from one medium to another caused by its change in speed.
  6. 8. Frequency-the number of waves that pass a point in a certain period of time
  7. 9. radiation- consists of waves of the electromagnetic (EM) field, which propagate through space and carry momentum
