Optics-Lenses-- 1cm thick glass slide is perpendicularly set I dunno how to do the question below. It doesn't say whether the whole system in in the air or in a more refractive "environment" (i.e. submerged in oil). It too doesn't say the exact position where the lens is set, and I think that the exact place influences the formation of the new image!! Am I wrong?? By the way, the answer is C. A 1cm thick glass slide is perpendicularly set in an optic system, as shown in the picture http://www.flickr.com/photos/80147355@N05/7177962339/sizes/m/in/photostream/ [Broken] A monochromatic light is used to form the image. What happens to the image when glass is set? a) Nothing happens, the image doesn't move. b) The new image is closer to the lens. c) The new image is farther from the lens. d) No image is formed. e) Two real images are formed, and they're less than 1cm distant from each other.
