Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Lead glass contains lead oxide \((PbO)\), which increases refractive index and brilliance.
Step 1: Lead oxide makes glass dense and optically brilliant.
Step 2: It also increases the refractive index of glass.
Step 3: Because of high refractive index, lead glass is useful in optical applications.
Step 4: Therefore, lead glass is commonly used for optical lenses and optical components. Hence, the correct answer is: \[ \boxed{\text{Optical lenses}} \]
