Solution

Definition of monochromatic beam: Monochromatic lights are single-wavelength lights, where mono means single, and chroma signifies color.
Diagrammatic representation:

3. Conclusion: When a monochromatic beam of light undergoes minimum deviation through an equilateral glass prism, then the beam passes parallel to the base of the prism.
