Question

how can the real image of a object can be obtained with convex mirror

Answer 1

$\bf\large\color{blue}\mathcal{HEY\:\:FRIEND\:\:}\bf\mathbb{:)}$

$\bf\texttt{Convex\:mirror}$ never forms a Real Image as the rays of light never converge.[They are projected backwards to get a virtual image]

Same is the case with $\bf\texttt{Plane\:Mirror}$

Only $\bf\texttt{Concave\:mirror}$ is capable of forming Real Images when object is at Focus or beyond it.

Hope this helps!!!!
