Which statement about specular reflections is true?

• A. True
• B. False
• C. Cannot tell
• D. Sometimes true

Answer: (A)

Specular reflections are mirror-like reflections that follow the law of reflection: the angle of incidence equals the angle of reflection. When a surface is smooth on the scale of the light’s wavelength, incoming rays reflect in a single, well-defined direction, producing a clear image like in a mirror. That predictable, direction-specific behavior is why the statement about specular reflections being true is correct. If a surface is rough, reflections become diffuse, with light scattered in many directions, but the fundamental rule—each microfacet still obeys the angle of incidence equals the angle of reflection—explains why specular reflections produce a sharp image only on smooth surfaces.
