How does the angle at which a ray of light strikes a prism compare with the angle at

    Prism Entry and Exit

    How does the angle at which a ray of light strikes a prism compare with the angle at which it passes out the other side?

    I think its the same...?

    I'm sure you can google that one :D i think it would be fast if your not sure
    there are only a fixed amount of outcomes for the action of passing a light ray into a prism you could allways make a list of them then use logical thinking to find the % of the chance of each out come but its allways a gussing game with that i suggest a simple google search :D

    The Answer ??

    Hey could something help me. I think the answer to my question is the angle is the same, but not positive..

    Thanks

    The angle of incidence is the same as the angle of reflection.

    Note that the light is not being reflected, rather it is being refracted as it passes through the prism. Google what refraction is, and you should know the answer to your question.

    it bends downward or upward?

    When light is passed through a prism, each of the different wavelengths that make up white light refract differently because their indices of refraction of are different. Hence when you pass white light through a prism it is separated into its colours.

    This is what is needed to be answered. I believe that the angle that passes out the other side is refracted? ??

    Exactly, after light passes through a prism, it deviates from its incident.
