Ah k..



Small question, in the line that is drawn, why can't it be the other way around.
Instead of starting from down and going up through G, can it start from the top and go down through G?

No read the question: It says" Start E' below the line EGF"

4)c you need to draw triangle but inverted (upside down)
explanation: because an image is always inverted unless its nearer than the first focal point to the lens

ignore what i said, probably wrong, because i dont seem to see any focal point or something similar

 

[imperial]

someone solve this 4)c question, im confused why its not smaller or bigger??

I suppose we can make it smaller or bigger. As it's only for 1 mark what's really important is that it should be inverted.

makes sense

 

[Maz]

makes sense

Another thing, earlier in the question it says that one of the images is diminished, and the question asks us "one" of the images.So, if we make smaller or larger, both are still "one" of the images.
[Hope that isn't confusing you]
