Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Lustre is an important physical property of minerals. It describes how light is reflected from the surface of a mineral.
Step 1: Understand lustre.
Lustre is the appearance or shine of a mineral surface.
Step 2: Relation with light.
Lustre depends on reflected light from the mineral surface. \[ \text{Lustre}=\text{appearance in reflected light} \]
Step 3: Final answer.
Thus, lustre is defined as the appearance of a mineral in reflected light. \[ \therefore \text{Correct Answer is (C)} \]
