The concept of brightness or brilliance is associated with which concept?

• A. Radiance
• B. Purification
• C. Purity
• D. Illumination

Answer: (B)

Brightness or brilliance is best described by radiance. Radiance refers to the visible intensity of light emitted from a source—the glow and shimmering quality that makes something appear bright. It captures that lively, shining aspect people mean by brilliance. Illumination is related but describes the effect of lighting a space rather than the inherent brightness of the source itself. Purification and purity deal with cleanliness, not light. So radiance is the term that most directly matches brightness or brilliance.
