We know that Concave mirror is converging in nature but If it is seen that rays after reflection from concave mirror have become parallel instead of getting converged then in this case where must have been the object placed?

Q. Light rays that are parallel to principal axis of concave mirror get converged at a particular point. It is called principal focus.Type 1 for true and 0 for flase

A concave mirror can converge parallel beams of light at one point. But rays originating from the focus after reflection does not always travel parallel to the principal axis.

A concave mirror can converge a parallel beam of light to a point. The reflection taking place, in this case, is a regular reflection.

Q. A beam of parallel rays is incident on a concave mirror such that they make a very small angle
