Across
- 3. when an object wiggles when it hears its natural frequency
- 6. the range of wavelengths or frequencies over which electromagnetic radiation extends
- 8. a rectilinear ray of light that strikes a surface
- 9. the angle between the direction of motion of the oncoming wave and perpendicular to the reflecting surface
- 11. measure of the bending of a ray of light when passing from one medium to another
- 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)
- 14. the angle between the direction of motion of the wave and a line drawn perpendicular to the reflecting boundary
- 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
- 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)
- 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
- 19. the spreading out of waves as they pass through an aperture or around objects
Down
- 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. our ear’s response to the frequency of sound
- 4. n1sinθ1 = n2sinθ2
- 5. bending light when it enters or exits a material
- 7. property of certain electromagnetic radiations in which the direction and magnitude of the vibrating electric field are related in a specified way
- 10. when a wave reflects off a plane surface, the angle of incidence is equal to the angle of reflection
- 12. single-wavelength lights
- 16. a ray of light or another form of radiant energy that is thrown back from a nonpermable or a nonabsorbing surface
