Across
  1. 3. A wave consisting of oscillating electric and magnetic fields that can travel through empty space without a physical medium
  2. 5. A space that contains absolutely no matter, meaning mechanical waves like sound cannot travel through it
  3. 10. The entire range of all types of electromagnetic radiation, ordered by wavelength, frequency, and energy
  4. 11. The bending of a wave as it passes from one medium to another because the speed of the wave changes
  5. 12. The number of waves that pass a fixed point in one second, measured in Hertz (Hz)
  6. 13. The maximum displacement from the equilibrium (rest) position, which is directly related to the energy of the wave
  7. 15. The distance between two consecutive identical points on a wave, such as from one crest to the next
Down
  1. 1. A wave that requires a medium (matter) to vibrate through, such as a sound wave or water wave
  2. 2. A wave where the medium moves back and forth in the same direction the wave travels, also known as a compression wave
  3. 4. The transfer of energy from a wave to the medium through which it is passing
  4. 6. A disturbance that transfers energy through space or a medium without transferring matter
  5. 7. The standard unit of measurement for frequency, representing one wave cycle per second
  6. 8. A wave in which the medium moves at right angles (up and down) to the direction the wave travels
  7. 9. The substance—such as a solid, liquid, or gas—through which a wave travels
  8. 14. The change in direction or bouncing back of a wave when it strikes a surface
