    Answer:

    1.33

    Explanation:

    For an optical instrument, the magnification ratio of the apparent diameter of the image to that of the object.

    Mathematically, from the given information;

    Magnification= \dfrac{n_{water}}{n_{air}}

    where;

    n_{water} =1.33\\ \\ n_{air} = 1.00

    = \dfrac{1.33}{1.00} \\ \\= \mathbf{1.33}
