Question

which of the two has great power a lens of short focal length or a lens of large focal length​

Answer 1

I think the lens which one is less focal length but I am not confirmed

Answer 2

the answer is lens of short focal length .

because:-

as p=1/f

that means power is inversely propertional to focal length

so,if focal length is short the power of lens is great

hope you got it
