Light Quiz TWO


Light Quiz 2


This is your second try!




  1. The electromagnetic spectrum consists of


  2. Visible Light

    Xrays

    UV light

    All of the above

    None of the above



  3. Light travels


  4. in straight lines.

    and bends as it goes through different mediums.

    and bounces at the same angle a ball does.

    All of the above.

    None of the above



  5. White light consists of


  6. all of the electromagnetic spectrum.

    a mixture of the colors red, yellow, and blue.

    many wavelengths.

    All of the above

    None of the above.



  7. Wavelengths


  8. affect each retinal cell the same.

    affect retinal cells differently.

    are reflected off the retinal cells.

    are not sensed by the retinal cells.

    None of the above.



  9. In order to see an object,


  10. it can not scatter light.

    it must give off (emit) light.

    it can reflect light.

    All of the above.

    None of the above.



  11. The angle of reflection


  12. is why we see red colors.

    is equal to the angle of incidennce.

    describes how we see the moon.

    All of the above.

    None of the above.



  13. Lenses are used


  14. in microscopes, cameras, and telescopes.

    to magnify.

    in the eye.

    All of the above.

    Two of the above.



  15. Transmitted light


  16. describes light coming from a source.

    is absorbed by objects.

    is relfected on transluscent objects.

    describes light going through transparent and transluscent objects.

    All of above.



  17. Red light


  18. transmitted through an object allows you to see it as red.

    lets you see an object as green when sensed by retinal cells.

    lets you see an object as red if refelcted.

    absorbed by an object allos you to see it as red.

    All of the above.



  19. Refraction of light


  20. happens to make a pencil seem to bend in a glass of water.

    causes magnification.

    is why we see reainbows with prisms and raindrops.

    All of the above.

    None of the choices.



When done, take your result page and save (on Mac: go to "print" but use "PDF" in lower left corner to save it). Then email to me as an attachment.
