    Hi PeacefulPumpkin8091 😁

    Thanks for your question!


    You're almost there! You have to correct your third scheme.


    To have a situation of total internal reflection, you need to satisfied this condition : the index of refraction of the first medium, water, is higher than the index of refraction of the second medium, air.

    I let you the conceptsheet on this notion here.


    Also, your first and second schemes need to be a bit modified.

    The angle of the refracted ray need to be higher than the incident ray, because you initially are in a more refractive medium.
