The focal length, image distance, and object distance are all connected in the lens formula for concave and convex lenses. The formula 1/f = 1/v + 1/u can be used to establish this link. The focal length of the lens is f, and the distance of the generated image from the lens' optical centre is v in this equation.
The lens equation or lens formula is an equation that links the focal length, image distance, and object distance.
1/v - 1/u= 1/f
Lens formula 1/v - 1/u= 1/f is how it's written. where. v is the image's distance from the lens, u is the object distance and f is the focal length.
State lens making formula.
The relationship between a lens' focal length, the refractive index of its material, and the radii of curvature of its two surfaces is known as the lens maker's formula. Lens manufacturers use it to build lenses with a specific power from glass with a specific refractive index.
Focal length-
The focal length of an optical system is the inverse of the system's optical power; it measures how strongly the system converges or diverges light. A system with a positive focal length converges light, while one with a negative focal length diverges light.
Explaination:
A thin lens is defined as one whose thickness is insignificant in comparison to its curvature radii. The thickness (t) is significantly lower than the two curvature radii R 1 and R 2 .
The focal length, image distance, and object distance are all connected in the lens formula for concave and convex lenses. The formula 1/f = 1/v + 1/u can be used to establish this link.
The focal length of the lens is f, and the distance of the generated image from the lens' optical centre is v in this equation. Finally, u is the distance between an item and the optical centre of this lens.
