  1. What is the smallest spectrum of an electromagnetic spectrum?
    Te part visible to the human eye.
  2. When UV light hits glass, the atoms in it will ______?
    Resonate
  3. What kind of kind of light doesnt shine through glass?
    Infrared light.
  4. Opaqueness occurs when?
    Light is absorbed.
  5. When light hits an oval surface...
    if the angle is relative to the normal it will equal 20 degrees. If it is not relative to the surface than use the equation 2(90-x)
  6. Concave is and convex is
    )(
  7. Fuse reflection is
    when you see something perfectly in every direction.
  8. Refraction is the
    bending of light
  9. If you go from a high to low index refraction, the light bends
    away from the norm.
  10. Selective reflection
    The color you see is the color that isnt really there.
  11. Primary/Additive colors :
    Red Blue Green
  12. Subjective colors :
    Cyan Yellow Magenta
  13. Complimentary colors
    any two colors mixed to get white
  14. What is red's subjective color?
    Cyan
  15. What is green's subjective color?
    Magenta
  16. What is blue's subjective color?
    Yellow
  17. What happens when you mix all of the subjective colors?
    Black
  18. The color of the sky depends on
    the amount of moisture in the sky. (the more clear he sky, the more blue it is)
  19. When something moves up and down then left and right periodically it is called a
    vibration
  20. A vibration is in space and time is called a
    wave
  21. What are the  wave characteristices ?
    amplitude, wavelength, period, frequency, and speed
  22. The speed of sound is
    depends on the temperature
  23. Sound needs what to travel?
    a medium!
  24. Sound travels fastest in
    Steel (15) and water (5)
  25. What are two different types of waves?
    transverse and longitudinal.
  26. What is a transverse wave?
    When the direction of the waves go + (perpendicular) (heat wave, light wave)
  27. What is a longitudinal wave?
    When the direction of the wave is || (parallel) to its vibration ( compress and refraction) Sound wave is longitudinal
  28. Sound is described as
    pitch = frequency
  29. How fast something travels is its
    elasticity
  30. Anything above 20,000 Hz and below 20 Hz a human
    • cannot hear.¬†
    • 20,00 ultrasonic
    • 20 infrasonic
  31. How rigid and smooth something is depends on how the sound is
    reflected

    Rigid (sound is absorbed)
  32. Light travels fastest in
    air
  33. Speed of sound is
    V = 330 + .6Tc
