Light in air strikes one of the equal faces of a 45∘–45∘–90∘ glass prism (n=1.60) at an incident angle of 35∘ to the normal. After entering the prism, the beam reaches the hypotenuse face. Determine whether the beam exits the hypotenuse into air or undergoes total internal reflection at that face, and state the relevant interior angle at the hypotenuse to support your conclusion.
