Which property defines how much highlight shines from the object?

• A. Diffuse Color
• B. Specular
• C. Glossiness
• D. Opacity

Answer: (B)

The brightness of a highlight on a surface is governed by the specular reflection component. The specular property controls how much light is reflected in a mirror-like way, which directly determines how strong the highlight appears. Glossiness affects the sharpness of that highlight—higher glossiness creates a tighter, brighter spot, while lower glossiness makes it softer and more spread out. Diffuse color defines the base color under diffuse reflection, and opacity controls transparency, neither of which directly set the highlight’s intensity. So the parameter that defines how much highlight shines is the specular property.
