    Answer:

    The critical angle for a light ray traveling 36.9°

    Explanation:

    The critical angle for a light ray traveling is calculated by

    apply Brewster angle tanθ = nb / na

    where, nb is refractive index of surface

                na is the refractive index of water

    tan θ = 1.00 / 1.33

    tan θ = 0.7519

    θ = 36.9°

    Therefore, the critical angle for a light ray traveling 36.9°
