Homework Help: Light and different mediums

  1. Jul 8, 2011 #1
    When light waves travel from one medium (air) to the next (water), their velocity changes. Does their frequency change also? Or does the wavelength change?

    hi gkangelexa! :smile:

    the frequency stays the same

    (otherwise they wouldn't "join up" properly at the interface :wink:)​

    Doesn't white light, upon entering a prism, break into colors according to frequency?

    Respectfully,

    Hi Steve! :smile:

    Yup, but the colours are already there (as good ol' Sir Isaac showed :wink:) …

    the colours stay the same, but their speeds change, so they go through at different angles, and become separated.​
