Answer:
1. In regular reflection, a parallel beam of incident light is reflected as a parallel beam in one direction; while in diffuse reflection, a parallel beam of incident light is reflected in different directions.
2. The differences between Real and Virtual Images In the world of optics real and virtual images are often described as opposites. Real images are produced by intersecting rays while virtual images are produced by diverging rays. Real images can be projected on a screen while virtual ones cannot.
3.The hatching in a drawing of a mirror represents a non reflecting surface
