Chromatic aberration arises in thick lenses due to:
Chromatic aberration arises in thick lenses due to:
Show Hint
"Chroma" means color; chromatic aberration is always related to the dispersion of colors.
Updated On: Apr 28, 2026
- scattering of light
- refraction of light
- interference of light
- reflection of light
- dispersion of light
Show Solution
Verified By Collegedunia
The Correct Option is
Solution and Explanation
Step 1: Concept
Chromatic aberration is a failure of a lens to focus all colors to the same convergence point.
Step 2: Analysis
The refractive index of a lens material varies with the wavelength (color) of light.
Step 3: Conclusion
This phenomenon, where different colors are refracted by different amounts, is known as dispersion. Final Answer: (E)
