What you learn in Theory:
When a light ray strikes the surface of a dispersing prism, it is refracted upon entering according to Snell's law and then passes through the glass until the second interface is reached.
What you learn in Practice:
The amount of light deviation by a prism is a function of the incident angle, the prism apex angle, and the refractive index of the material from which the prism is constructed.
