    reflection and rays

    The drawings show two arrows, A and B, that are located in front of a plane mirror. A person at point P is viewing the image of each arrow.

    Which images can be seen in their entirety? Determine your answers by drawing a ray from the head and foot of each arrow that reflects from the mirror according to the law of reflection and reaches point P. Only if both rays reach point P after reflection can the image of that arrow be seen in its entirety.

    so which one is correct?

    image of A
    image of B
    or neither image

    I would say image of A?

    thanks for help on this one.

    I've modified your images a little bit to show you how to find the rays.

    Okay I think I was confused by the terminolgy. "entirety" do they mean the exact image reflected back?

    thats what I understood from this, and thanks for the new diagrams, fits the situation for the problem.

    thankyou.
