The reflection of light can be roughly categorized into two types of reflection: specular reflection is defined as light reflected from a smooth surface at a definite angle, and diffuse reflection, which is produced by rough surfaces that tend to reflect light in all directions (as illustrated in Figure 1).
Interactive Tutorial. Particle and Wave Reflection An excellent comparison of the wave and particle theories involves the differences that occur when light is reflected from a smooth, specular surface, such as a mirror.This interactive tutorial explores how particles and waves behave when reflected from a smooth surface.nteractive Tutorial.
