God bless you sir

How did you get 33

[@christineclement6941]

This was really helpful, man. Thanks!

Sign for a diverging lens is positive right?,converging lens id negative,you've taken the opposite

[@brettguisti5027]

Diverging lenses have negative focal lengths. They can only produce virtual images, which have negative image distances. The only way to always get a negative image distance, regardless of the object distance, is to have a negative focal length.

how did you get to 30 cm?

[@brettguisti5027]

-1/15 = -1/10 + 1/do, so 1/do = -1/15 + 1/10 = -2/30 + 3/30 = 1/30, then invert both sides to get do = 30

@@brettguisti5027where did u get all these numbers from

[@sokcreation3337]

how did u know that the image is virtual

[@calebcoudriet7275]

Since the rays didn't converge, the image is never formed on the other side of the lens. Instead, they can be traced backwards to a virtual image
