WebMar 6, 2024 · The focal point is a property of the lens. It is where parallel light would converge (in practice, that is light that "appears to come from infinitely far away"). As others pointed out, the lensmaker's formula describes how the object p and image q distance are related to this property of the lens. So you just measure p and q, and find f from WebThe focal length of the lens is the distance from the center of the lens to the spot, given to be 8.00 cm. Thus, 25.22 To find the power of the lens, we must first convert the focal length to meters; then, we substitute this value into the equation for power. This gives size 12 {P= { {1} over {f} } = { {1} over {0 "." "0800"" m"} } ="12" "."
