Solution

The correct option is B
False

A convex mirror is a divergent mirror and a concave mirror is a convergent mirror. Convex mirrors diverge rays of light that hit them and form a virtual image. Concave mirrors bring incoming parallel rays together and cause these rays to converge. Archimedes burnt ships by focusing sunrays on them using a large concave mirror when the Roman soldiers attacked his town Syracuse.
