Rainbows and prisms

  1. May 15, 2012 #1
    not knowing much of anything about light physics,

    is it possible to change the effects of a prism (the visible light refracted) if it were in an environment with different air composition than our normal environmental composition? or even different pressure?

    so instead of 14.7 psi, 21% oxygen, 78% nitrogen, et cetera, would the light transmit differently with more oxygen and higher/lesser atmospheric pressures?

    Although there would be slight effects due to these changes, as long as the density remained anywhere near what it is now, it wouldn't be noticeable.

    Optically, air is almost same as vacuum when compared to the prism. So it's mostly composition of the prism that will have an affect.
