Across
  1. 4. distance between one point on a wave and the nearest point moving with the same speed and direction
  2. 6. SI unit for frequency
  3. 7. waves that have to travel through a medium
  4. 9. waves that can travel through matter or an empty space, includes radio waves, infrared waves, visible light waves, ultraviolet waves, x rays, and gamma rays
  5. 10. matter that the wave travels through (air or water)
Down
  1. 1. mechanical wave that causes particles in matter to move at right angles to the direction the wave travels
  2. 2. mechanical causes the particles to move back and forth along the direction the wave travels
  3. 3. speed wavelength x frequency
  4. 5. for a transverse wave, one half the distance between a crest and a trough
  5. 8. number of wavelengths that pass a given point in one second, measured in hertz
