Virtual image

Light never travel back?

....READ THE BOOK PROPERLY DUDE!!!!!!DO U EXPECT THEM TO DO SUCH A ILLOGICAL THING AND THT TREND TO CONTINUE FOR AGES FOR A GUY NAMED PASUSHAH TO COME N SHOW SMARTNESS SAYING LIGHT DOESN"T TRAVEL BACK???? get some concepts in hand before pointing anytrhing out[13][14][15][16][16][16][16][16][16][16]

ok if u r lazy enough not to read properly read this:

IMAGE is a point where rays come from /appear to come from[our minds have such a programming of perception tht we always think light comes from a straight direction......so our minds interpret tht image is formed behind the mirror............but PRACTICALLY light is never reaching there]

Don't be so crude 25/6. He might be having some misconceptions. If u wanna clear it, good, but be soft atleast.

why the electric field due to a plane sheet of charge is same everywhere irrespective of distance of point of observation

who says light never travels back
the only condition that light rays follow (according to particle theory) is that it travels in straight lines
but in this case the light rays after reflection do not really intersect at that point (behind the mirror) ,ie you know is the case of virtual image .we see that virtual image due to ability of our eye lens(combination of convex and concave lens) to convert that virtual image into real image (through refraction) and thus we see the virtual image.
if our eyes won't have been able to see virtual images then importence of virtual images would have been very less in ray optics
