Chromatic aberration of lens can be corrected by
Text Solution
Verified by ExpertsThe correct answer is:
C
Step 1: Understand chromatic aberration. Chromatic aberration occurs because lenses have different refractive indices for different wavelengths of light. This results in different colors being focused at different points, leading to a blurred image.
Step 2: Analyze the options:
Therefore, the correct answer is C.
Step 2: Analyze the options:
- Option A: Reducing the aperture can reduce the amount of light entering, but it does not correct the distortion of colors caused by chromatic aberration.
- Option B: Proper polishing of the lens surfaces can improve clarity but does not address chromatic aberration itself.
- Option C: Suitably combining the lens with another lens of different materials or designs can effectively correct chromatic aberration. For instance, using an achromatic doublet which consists of a convex lens made from crown glass and a concave lens made from flint glass will bring two wavelengths into the same focus.
- Option D: Providing different curvatures does not inherently correct color distortion caused by varying refractive indices.
Therefore, the correct answer is C.
