GS-2 Physical Sciences Question 4

[rao.mudigo8389]

A.) I dont get why its a DIVERGING LENS (roman numeral III) and not a convergin lens....

formula-wise

diverging: f <0, di<0>0 and di>0
(by di, i mean distance of image)

so
1.) Converging:
1/f = 1/o + 1/i ; if o =f, then 1/f - 1/f = 1/i = not possible to view image

BUT
2.) Diverging:
-1/f = 1/o - 1/i; if o=f, then -1/f -1/f = 1/i = a possible number for i

I get the point that virtual images are only produced via a diverging lens, but mathematically a calculation isnt possible when I, II, and IV are applied as opposed to I, II, and III...

I agree with you. I'm confused as well.

[kim.dangal6935]

actually, IV doesn't make sense.

What does it mean by using the Diverging Lens as the "objective". Isn't the objective defined as the object?

I am confused too. This question doesnt make any sense at all. Can any of the makers of this test explain????
