Homework Help: Speed of light

  1. Mar 15, 2005 #1
    How can I determine the speed of light from a glass plate? I have the the numbers that I compared the average experimental value of the index of refraction with the general range of the index of refraction of glass.

    are you trying to find out speed of light though a glass plate? Im not sure what your question is.

    Regards,

    yes, that's correct.

    Is the problem to find the "speed of light (in vacuum)" or "the speed of light in the glass plate". The index of refraction is the ratio of speed of light in the glass plate to the speed of light in vacuum.

    V = C/N... c being speed of light (3x10^8) and N being being whatever the index of refraction is of the glass.
