Vedclass · Answer

(C) Chromatic aberration occurs because the refractive index $(\mu)$ of the lens material depends on the wavelength $(\lambda)$ of light. According to the lens maker's formula,the focal length $(f)$ is given by $\frac{1}{f} = (\mu - 1) \left( \frac{1}{R_1} - \frac{1}{R_2} \right)$. Since $\mu$ varies with $\lambda$ (Cauchy's equation),the focal length $f$ also varies with the wavelength of light. Therefore,different colors of light focus at different points along the principal axis,leading to chromatic aberration.
