    Answer:

    30.1^{\circ}

    Explanation:

    Refraction is a phenomenon that occurs when light passes through the interface between two mediums.

    When this occurs, the ray of light changes speed and also changes direction, according to Snell’s Law:

    n_1 sin \theta_1 = n_2 sin \theta_2

    n_1 is the index of refraction of the 1st medium

    n_2 is the index of refraction of the 2nd medium

    \theta_1 is the angle of incidence (the angle between the incident ray and the normal to the boundary)

    \theta_2 is the angle of refraction (the angle between the refracted ray and the normal to the boundary)

    For this problem we have:

    n_1=1.00 is the index of refraction of the 1st medium (air)

    n_2=1.41 is the  index of refraction of the 2nd medium

    \theta_1 =45^{\circ} is the angle of incidence

    Solving for the angle of refraction, we find:

    \theta_2 = sin^{-1}(\frac{n_1}{n_2}sin \theta_1)=sin^{-1}(\frac{1.00}{1.41}sin 45^{\circ})=30.1^{\circ}
