Vedclass · Answer

(C) The longitudinal chromatic aberration $(LCA)$ of a thin lens is given by the formula:$LCA = \omega 	imes f$where $\omega$ is the dispersive power and $f$ is the focal length of the lens.Given:Focal length $(f)$ = $20 \ cm$Dispersive power $(\omega)$ = $0.08$Substituting the values:$LCA = 0.08 	imes 20 \ cm$$LCA = 1.6 \ cm$Therefore,the longitudinal chromatic aberration is $1.6 \ cm$.

The focal length of a lens is $20 \ cm$ and its dispersive power is $0.08$. What is its longitudinal chromatic aberration in $cm$?
