Three students measured the focal length of a convex lens using parallel rays from a distant object. All of the measured the distance between the lens and the inverted image on the screen. (i) Student A saw a sharp image on the screen and labelled the distance as f_(1) (ii) Student B saw a slightly larger blurred image on the screen and labelled the distance as f_(2) (iii) Student C saw slightly smaller blurred image on the screen and labelled the distance as f_(3) The relation between the three measurements would most likely be :

1.	Three students measured the focal length of a convex lens using parallel rays from a distant object. All of the measured the distance between the lens and the inverted image on the screen. (i) Student A saw a sharp image on the screen and labelled the distance as f_(1) (ii) Student B saw a slightly larger blurred image on the screen and labelled the distance as f_(2) (iii) Student C saw slightly smaller blurred image on the screen and labelled the distance as f_(3) The relation between the three measurements would most likely be :
Answer» `f_(1) = f_(2) = f_(3)` `f_(1) LT f_(2) lt f_(3)` `f_(3) lt f_(1) lt f_(2)` `f_(1) lt f_(2)` and `f_(1) = f_(3)` Solution :NA
