At the second surface AC, the light ray exits from glass to air, bending away from the normal. This is in contrast to the first surface where the bending was towards the normal.
Describe the behavior of the light ray at the second surface AC as it exits the glass prism. How does it compare to the first surface?

As light exits the glass prism at the second surface AC, it undergoes refraction again. The behavior is similar to the first surface BD but in the opposite direction. The refracted light bends away from the normal, moving towards the base of the prism. However, the extent of deviation depends on factors like the angle of incidence and the refractive index of the prism material. Generally, the second refraction at surface AC continues the dispersion of colors initiated at the first surface, resulting in the formation of a spectrum as white light exits the prism.
