Answer:
(i) Focal length of the concave mirror remains unchanged. (ii) As \[f=\frac{1}{\mu -1}\] For \[{{\lambda }_{2}}>{{\lambda }_{1}},\] \[{{\mu }_{2}}<{{\mu }_{1}},\] \[\therefore \] \[{{f}_{2}}>{{f}_{1}}\] i.e., when wavelength of incident light is increased, focal length of the convex lens increases.
