Real Image: It can be focused on a screen and captured on a film or sensor. The object and the image will be on the same side of the mirror. There is no lateral inversion of the image. Virtual Image: We can only see this but cannot focus it on a screen. It will appear behind t...
The image formation of a point source is either real, virtual or mixed according to the position of the source with respect to the mirror. If the ratio of the diameter of the mirror to its radius is at least 2:3, the mirror does not provide virtual image formation. Point sources, the...
Convex Mirror Image Formation Convex mirrors always produce a virtual and upright image. The following are the several sorts of object placement in a convex mirror: –> When a thing is put at infinity, it is said to be infinite. –> When an object is put between the pole and infinity, ...
When you place the concave mirror on the holder in front of the light source (the light box which has a hole), you should move the mirror nearer and farther until an image of the hole is formed next to it and is equal to it, and you can measure the distance between...
Image formation by plane mirrorSpherical mirrorThese mirrors are highly polished surfaces that are cut as part of a sphere. One side of the spherical mirror is a reflecting surface and the other side is silvered. The middle part of the spherical mirror is the pole. The center of the ...

Next, the fluorescence properties of both PDMI-PFP and PEG43-b-P(NIPAM21-co-PDMI9) in THF were examined by fluorescence spectroscopy (red and blue dashed lines, Fig.1a). The monomeric amine-reactive perylene derivative PDMI-PFP displayed a nearly mirror image relationship between the fluorescenc...

one of the shells may form the end of the tube adjacent which the fluorescent screen is mounted and the mirror may form part of the wall of the enlargement of the tube within which the screen lies. When the mirror and shell are used in the manner described, they must be made of materi...
