Question

In chromatic aberration of a convex lens

• A. the image of straight object becomes wavy.
• B. the image of white object becomes coloured and blurred.
• C. both $\left(a\right)$ and $\left(b\right)$
• D. none of the above.

Answer 1

The correct option is B the image of white object becomes coloured and blurred.

Chromatic aberration is caused by lens dispersion, with different colors of light travelling at different speeds while passing through a lens. As a result, the image can look blurred or noticeable colored edges (red, green, blue, yellow, purple, magenta) can appear around objects, especially in high-contrast situations.

Hence, option $\left(b\right)$ is the correct answer.
