Re: [ATM] ATM chinese puzzler



Hallo,
Perhaps he only tested for stray light. He needs a  flashlight shining 
on the mirror, the reflected picture of the light gathers to a picture 
of the light. He covers the picture of the directly reflected light. So 
he only looks at the remaining stray light. I do this test to decide if 
the mirror is completely polished. So there should be some steps 
following, incl. Foucault.
Sincerely Marty
