Consider a ray at the interface air and glass

  1. Jun 12, 2008 #1
    Consider a ray at the interface air and glass (n = 1.5). We know that incident angle i and refracted angle r are related by sin i = 1.5 sin r

    Can we some how show the relationship between i and r is r = m i + c (straight line)?

    If you look at the following data, it follows the Snell's law and r = 0.6 i + 1.

    i r
    10 7
    20 13
    30 19
    40 25
    50 31

    Hoping this is not an homework, write r as function of i using Snell's law, then develop the functions sin and arcsin to the appropriate order (in radians), considering that 50° are less than 1 radian.
