Is it possible to arrange a setup in which a convex mirror forms a real image(i.e an image that can be obtained on a a screen.)
Imagine a setup in which light from infinity falls on a concave mirror and the mirror converges it on the focus.(f would be negative)
However, if we put a convex mirror before the focus of the concave mirror,then the light rays will not actually meet, and the focus of the concave mirror(where the light would have normally converged if we had not placed a convex mirror) will act as a virtual object for the convex mirror.
In this situation, u (object distance) is positive and and so is the focal length of the convex mirror.
From the mirror equation, v=f*u/u-f For this value to be negative,f>u(where f if focal length of convex mirror) so that a real image is formed. But can this be practically done in the lab?How can we choose different sizes of mirrors and screen so that they do not block the light rays? I tried doing it but it did not work out. Can someone help and maybe suggest another setup.
