A glass is located in front of concave mirror as shown in figure. The gap between mirror and glass is neglected. In this conditions, where is the final image of matter? http://i26.tinypic.com/2a6w6es.jpg The answer of above problem is not match with mine. I need help. I draw the beams as below, since the gap between mirror and the glass neglected, i think the figure is approximately the same as above. http://i31.tinypic.com/2yplsif.jpg If the roads of beam right then the final image of matter is between focus and center of curvature. But the book say it is far from center of curvature. What do you think?
