WAVES

12345678910
Across
  1. 4. for a transverse wave, one half the distance between and a trough
  2. 5. mechanical wave that causes particles in matter to move at right angles to the direction the wave travels
  3. 8. waves that have to travel through a medium (matter that a wave travels through)
  4. 10. SI unit for frequency
Down
  1. 1. waves that can travel through matter or empty space, includes radio waves, infrared waves, visible light waves, ultra violet waves, x rays, and gamma rays
  2. 2. mechanical causes the particles to move back and forward along the direction the wave travels
  3. 3. number of wavelengths that pass a given point in one second, measured in hertz
  4. 6. distance between one point on a wave and the nearest point moving with the same speed and direction
  5. 7. disturbance that moves through matter and space and carries energy
  6. 9. wavelength x frequency
