Answer:

power is defined as any emergent point of final rays to intresect in real. ...

Explanation:

but as you see here the rays are initially also parallel and after also parallel...that it seems as there is nothing divergence or convergence occurs....just like a parallel glass slab..

though....for image formation we virtually converge the rays ...after refraction..

but net affect finally its parallel to initial...

Power=0

or 1/f=0
