Question

10. A ray of light traveling in air is incident at angle ? on one face of a 90° glass prism. Part of the light refracts into the prism and strikes the opposite face at point A, as shown. If the ray at A is at the critical angle for total internal reflection, what is the value of ?? (HINT: The answer does not depend on the glass's index of refraction.)
