Question

derive the lens formula​

Answer 1

Answer:

Hola!

Derive lens formula v1−u1=f1 .

Derive lens formula v1−u1=f1 .From the geometry of the figure above, right angled △ ABO and △ ABO are similar. Similarly, from the geometry of the figure above, right angled △ODF2 and △BAF2 are similar. This equation is called the 'Lens formula'.

Lens Formula Derivation

Consider a convex lens with an optical center O. Let F be the principle focus and f be the focal length. An object AB is held perpendicular to the principal axis at a distance beyond the focal length of the lens. A real, inverted magnified image A’B’ is formed as shown in the figure.
