Best ResponseYou've already chosen the best response.0wat si the type of lens that magnifies ur imge and also produces a virtual image? answer this question then wat is the ray diagram for getting image at infinity with that type of lens? wat is lens formula relating f,u,v i can get my v from that? wat is magnification? in terms of u and v u are near the answer once u have ansered all these questions

Best ResponseYou've already chosen the best response.0The lens must be a convex lens. The object is at focus.

Best ResponseYou've already chosen the best response.0m = f/(f+u) = 5/(5+5) = 0.5?????

Best ResponseYou've already chosen the best response.0Its given that, m = v/u = h1 / h2

Best ResponseYou've already chosen the best response.0yeah so u know u, find V using lens formula then apply u/v to find magnification(the extent to which the image is magnified w.e.to object) the key here is taht u=focal length that u will come to know ONLY WHEN U DRAW THE RAY DIAGRAM!

Best ResponseYou've already chosen the best response.01/f=1v1/u 1/v=1/f+1/u by sign convention f=5 u=5

Best ResponseYou've already chosen the best response.0@salini didi, then, m = f/(f+u) = 5[5 + (5)] = 5/0?????
