Consider two isosceles prisms \( 1 \) and \( 2 \) with prism angles \( A_1 \) and \( A_2 \) and refractive indices \( n_1 \) and \( n_2 \), respectively, as shown in the figure. The faces \( a_1 b_1 \) and \( a_2 b_2 \) are parallel to each other and perpendicular to the mirror \( M \). If a ray of light is incident on the face \( a_1 c_1 \) and emerges from the face \( a_2 c_2 \), then the correct statement(s) is/are:
