Question

write lens formula and expain the terms in it​

Answer 1

Answer:

1/v - 1/u = 1/f

Explanation:

Here, "v" is the distance of the image from the optical center of the lens, "u" is the distance of the object from the optical center of the lens and "f" is the focal length of the lens

Answer 2

Lens maker formula is the formula for the manufacturer of lenses. ... this is the formula, f = focal length, 1/f = power of lens, R1 and R2 are radii of curvature. μ = refractive index of glass used. R1, R2 and f are quantities, positive in the direction of light rays.
