Specular reflection can occur on which surface type?

Explanation:
Specular reflection happens when light encounters a surface that is smooth on the scale of the light’s wavelength, so each incoming ray reflects in a single, predictable direction and can form a clear image. A mirror is designed to be that smooth, polished surface, so it produces a strong, specular reflection. The other surfaces—fuzzy fabric, porous concrete, and matte paper—have rough, irregular textures that scatter light in many directions. This diffuse reflection washes out a coherent image, so they don’t produce specular reflection. Therefore, the surface that yields a specular reflection is the mirror.
