Angle of refraction

    1. The problem statement, all variables and given/known data
    Qsbpq9uJtSjjW9u02cfB15hCV8Ru_UDyGOr6EARDLDXQzEpUYeWlcg_XBTdwS863jFltmT7FF4b_iHfnRVnKXNREgjMZyCGo.png

    I need to find how a ray of light will travel from the snail towards Andrews eye.
    I need to find the angle of incidence and angle of refraction.
    I know the index of refraction of both materials
    Air: 1
    Water 1.33
    2. Relevant equations
    Snells law
    1.33 *sin(X) = sin(y)
    x is angle of incidence
    y is angle of refraction

    3. The attempt at a solution
    I only know how to solve these problems when I have a normal line
    How do I find the normal line

    Hello IBNU1. Welcome to PF .

    Do you have any dimensions for this ?

    Sorry I forgot to include them
    The depth of the water is 5m and the distance from his eye to the snail is 25 m

    I seems to me that you need to know more than that.
