Re: Double concave mirror toy

Tell us more about this. The real image of what? How
was that image produced? The real image where (or on
what)? Was the reflected beam only a tiny fraction of
the incident beam or was it a big fraction? How was
the incident laser beam directed with respect to rays
making the real image? How was the reflected beam
directed? What happens when the real image becomes
fuzzy? Does the reflected beam disappear when the
light producing the real image is turned off?
