Across
  1. 3. when an object wiggles when it hears its natural frequency
  2. 6. the range of wavelengths or frequencies over which electromagnetic radiation extends
  3. 8. a rectilinear ray of light that strikes a surface
  4. 9. the angle between the direction of motion of the oncoming wave and perpendicular to the reflecting surface
  5. 11. measure of the bending of a ray of light when passing from one medium to another
  6. 13. the apparent increase/decrease in frequency of a certain sound wave depending on the position that the object producing said sound waves is in regards to you (ex: a firetruck siren passing by sounds like a normal siren, but when it passes you and heads in the opposite direction the pitch of the siren sounds deeper/lower, though not actually changing)
  7. 14. the angle between the direction of motion of the wave and a line drawn perpendicular to the reflecting boundary
  8. 15. the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just one angle as in the case of specular reflection
  9. 17. the apparent increase/decrease in frequency of a certain light wave depending on the position that the object producing said light wave is in regards to you (ex: stars in outer space that are closer look blue, while farther stars appear red, though the colors of the stars aren't much different)
  10. 18. the change in direction of a wavefront at an interface between two different media so that the wavefront returns back to the medium from which it originated
  11. 19. the spreading out of waves as they pass through an aperture or around objects
Down
  1. 1. reflection such that the angle of reflection of the light is equal to the angle of incidence and on the opposite side of the normal to the point of incidence
  2. 2. our ear’s response to the frequency of sound
  3. 4. n1sinθ1 = n2sinθ2
  4. 5. bending light when it enters or exits a material
  5. 7. property of certain electromagnetic radiations in which the direction and magnitude of the vibrating electric field are related in a specified way
  6. 10. when a wave reflects off a plane surface, the angle of incidence is equal to the angle of reflection
  7. 12. single-wavelength lights
  8. 16. a ray of light or another form of radiant energy that is thrown back from a nonpermable or a nonabsorbing surface
